Use word processing in a sentence

I. An Introduction to Word Processing

Word processing is the act of using a computer to transform written, verbal, or recorded information into typewritten or printed form. This chapter will discuss the history of word processing, identify several popular word processing applications, and define the capabilities of word processors.

Of all the computer applications in use, word processing is by far the most common. The ability to perform word processing requires a computer and a special type of computer software called a word processor. A word processor is a program designed to assist with the production of a wide variety of documents, including letters, memoranda, and manuals, rapidly and at relatively low cost. A typical word processor enables the user to create documents, edit them using the keyboard and mouse, store them for later retrieval, and print them to a printer. Common word processing applications include Microsoft Notepad, Microsoft Word, and Corel WordPerfect.

Word processing technology allows human beings to freely and efficiently share ideas, thoughts, feelings, sentiments, facts, and other information in written form. Throughout history, the written word has provided mankind with the ability to transform thoughts into printed words for distribution to hundreds, thousands, or possibly millions of readers around the world. The power of the written word to transcend verbal communications is best exemplified by the ability of writers to share information and express ideas with far larger audiences and the permanency of the written word.

The increasingly large collective body of knowledge is one outcome of the permanency of the written word, including both historical and current works. Powered by decreasing prices, increasing sophistication, and widespread availability of technology, the word processing revolution changed the landscape of communications by giving people hitherto unavailable power to make or break reputations, to win or lose elections, and to inspire or mislead through the printed word.

Word Processing

Word processing software can easily create, edit, store, and print text documents such as letters, memoranda, forms, employee performance evaluations (such as those in Appendix A), proposals, reports, security surveys (such as those in Appendix B), general security checklists, security manuals, books, articles, press releases, and speeches. A professional-looking document can be easily created and readily updated when necessary.

The length of created documents is limited only by the storage capabilities of the computer, which are enormous. Also, if multiple copies of a working document exist, changes to it should be promptly communicated to all persons who use the document. Specialized software, using network features, can be programmed to automatically route changes to those who need to know about updates.

II.D.2.c. Rendering Systems

Alternatives to providing software with appropriate character rendering systems include providing graphic files or elaborate formatting (e.g., backwards typing of Arabic and/or typing of Arabic with hard line breaks). However, graphic files are cumbersome to download and use, are space consuming, and cannot be electronically searched except by metadata. The second option of elaborate formatting often does not look as culturally appropriate as properly rendered text, and usually loses its special formatting when text is added or is upgraded to a new system. It is also difficult and time consuming to produce. Note that Microsoft Word 2000 and Office XP support the above rendering systems; Java 1.4 supports the above rendering systems except for vertical text.

15.3.2 Abbreviation Expansion

Popular word processing programs often include abbreviation expansion capabilities. Abbreviations for commonly used text can be defined, allowing a long sequence such as an address to be entered with just a few keystrokes. With a little investment of setup time, those who are able to remember the abbreviations they have defined can find this a useful technique. Abbreviation expansion schemes have also been developed specifically for people with disabilities (Moulton et al., 1999; Vanderheiden, 1984).

Automatic abbreviation expansion at phrase/sentence level has also been investigated: the Compansion (Demasco & McCoy, 1992; McCoy et al., 1998) system was designed to process and expand spontaneous language constructions, using Natural Language Processing to convert groups of uninflected content words automatically into full phrases or sentences. For example, the output sentence “John breaks the window with the hammer” might derive from the user input text “John break window hammer” using such an approach.

With the rise of text messaging on mobile devices such as mobile (cell) phones, abbreviations are increasingly commonplace in text communications. Automatic expansion of many abbreviations may not be necessary, however, depending on the context in which the text is being used. Frequent users of text messaging can learn to recognize a large number of abbreviations without assistance.

Altered evidence and spoliation

Finding the discrepancies or modifications of an electronic file can only be accomplished if there is a comparison to be made with the original file. Using Figure 11.5 as an example, given that the file having the MD5 hash value of d41d8cd98f00b204e9800998ecf8427e is the original, and where the second file is the alleged altered file, a visual inspection of both files should be able to determine the modifications. However, when only file exists, proving the file to be unaltered is more than problematic, it is virtually impossible.

In this situation of having a single file to verify as original and unaltered evidence, an analysis would only be able to show when the file was modified over time, but the actual modifications won’t be known. Even if the document has “track changed” enabled, which logs changes to a document, that would only capture changes that were tracked, as there may be more untracked and unknown changes.

As a side note to hash values, in Figure 11.5, the hash values are completely different, even though the only difference between the two sample files is a single period added to the text. Any modification, no matter how minor, results in a drastic different hash value.

The importance in validating files in relation to the identification of a suspect that may have altered a file is that the embedded metadata will be a key point of focus and avenue for case leads. As a file is created, copied, modified, and otherwise touched, the file and system metadata will generally be updated.

Having the dates and times of these updates should give rise to you that the updates occurred on some computer system. This may be on one or more computers even if the file existed on a flash drive. At some point, the flash drive was connected to a computer system, where evidence on a system may show link files to the file. Each of these instances of access to the file is an opportunity to create a list of possible suspects having access to those systems in use at each updated metadata fields.

In the Microsoft Windows operating systems, Volume Shadow Copies may provide an examiner with a string of previous versions of a document, in which the modifications between each version can be determined. Although not every change may have been incrementally saved by the Volume Shadow Service, such as if the file was saved to a flash drive, any previous versions that can be found will allow to find some of the modifications made.

Where a single file will determine the outcome of an investigation or have a dramatic effect on the case, the importance of ‘getting it right’ cannot be overstated. Such would be the case of a single file, modified by someone in a business office, where many persons had common access to the evidence file before it was known to be evidence. Finding the suspect that altered the evidence file may be simple if you were at the location close to the time of occurrence. Interviews of the employees would be easier as most would remember their whereabouts in the office within the last few days. Some may be able to tell you exactly where other employees were in the office, even point the suspect out directly.

But what if you are called in a year later? How about 2 or more years later? What would be the odds employees remembering their whereabouts on a Monday in July 2 years earlier? To identify a suspect at this point requires more than a forensic analysis of a computer. It will probably require an investigation into work schedules, lunch schedules, backup tapes, phone call logs, and anything else to place everyone somewhere during the time of the file being altered.

Potentially you may even need to examine the hard drive of a copy machine and maybe place a person at the copy machine based on what was copied at the time the evidence file was being modified. When a company’s livelihood is at stake or a person’s career is at risk, leave no stone unturned. If you can’t place a suspect at the scene, you might be able to place everyone else at a location, and those you can’t place, just made your list of possible suspects.

Trusting Spelling and Grammar Checkers

We often see evidence that users of word processing systems trust absolutely in spelling and grammar checkers. From errors in business letters and on resumes to uncorrected word usage in academic papers, this nonstrategy emerges as epidemic. It underscores a pattern of implicit trust that if a word is not flagged as incorrect in a word processing system, then it must be not only spelled correctly but also used correctly. The overarching error is trusting the digital checking system too much, while the underlying functional problem is that such software identifies gross errors (such as nonwords) but cannot discriminate finer nuances of language requiring judgment (like real words used incorrectly). Users from average citizens to business executives have become absolutely comfortable with depending on embedded spelling and grammar checkers that are supposed to autofind, trusting the technology so much that they often do not even proofread. Like overtrust of security monitoring, these personal examples are instances of reduced vigilance due to their implicit belief that the technology is functionally flawless, that if the technology has not found an error, then an error must not exist.

Template Development

Certification Packages consist of a set of documents that all go together and complement one another. A Certification Package is voluminous, and without standardization, it takes an inordinate amount of time to evaluate it to make sure all the right information is included. Therefore, agencies should have templates for all the documents that they require in their Certification Packages. Agencies without templates should work on creating them. If an agency does not have the resources in-house to develop these templates, they should consider outsourcing this initiative to outside consultants.

The later chapters in this book will help you understand what should be included in each of these types of documents. Some agencies may possibly require other types of documents as required by their information security program and policies.

Templates should include guidelines for what type of content should be included, and also should have built-in formatting. The templates should be as complete as possible, and any text that should remain consistent and exactly the same in like document types should be included. Though it may seem redundant to have the exact same verbatim text at the beginning of, say, each Business Risk Assessment from a particular agency, each document needs to be able to stand alone and make sense if it is pulled out of the Certification Package for review. Having similar wording in like documents also shows that the packages were developed consistently using the same methodology and criteria.

With established templates in hand, it makes it much easier for the C&A review team to understand what it is that they need to document. Even expert C&A consultants need and appreciate document templates. Finding the right information to include the C&A documents can by itself by extremely difficult without first having to figure out what it is that you are supposed to find—which is why the templates are so very important. It’s often the case that a large complex application is distributed and managed throughout multiple departments or divisions and it can take a long time to figure out not just what questions to ask, but who the right people are who will know the answers.

I.B. Capabilities and Limitations of Automatic Speech Recognition

ASR is currently used for dictation into word processing software, or in a “command-and-control” framework in which the computer recognizes and acts on certain key words. Dictation systems are available for general use, as well as for specialized fields such as medicine and law. General dictation systems now cost under $100 and have speaker-dependent word-recognition accuracy from 93% to as high as 98%. Command-and-control systems are more often used over the telephone for automatically dialing telephone numbers or for requesting specific services before (or without) speaking to a human operator. Telephone companies use ASR to allow customers to automatically place calls even from a rotary telephone, and airlines now utilize telephone-based ASR systems to help passengers locate and reclaim lost luggage. Research is currently being conducted on systems that allow the user to interact naturally with an ASR system for goals such as making airline or hotel reservations.

Despite these successes, the performance of ASR is often about an order of magnitude worse than human-level performance, even with superior hardware and long processing delays. For example, recognition of the digits “zero” through “nine” over the telephone has word-level accuracy of about 98% to 99% using ASR, but nearly perfect recognition by humans. Transcription of radio broadcasts by world-class ASR systems has accuracy of less than 87%. This relatively low accuracy of current ASR systems has limited its use; it is not yet possible to reliably and consistently recognize and act on a wide variety of commands from different users.

20.7 Software Tools for Making Wireframes

Wireframes can be sketched using any drawing or word processing software package that supports creating and manipulating shapes. While many applications suffice for simple wireframing, we recommend tools designed specifically for this purpose. We use Sketch, a drawing app, to do all the drawing. Craft is a plug-in to Sketch that connects it to InVision, allowing you to export Sketch screen designs to InVision to incorporate hotspots as working links.

In the “Build mode” of InVision, you work on one screen at a time, adding rectangular overlays that are the hotspots. For each hotspot, you specify what other screen you go to when someone clicks on that hotspot in “Preview mode.” You get a nice bonus using InVision: In the “operate” mode, you, or the user, can click anywhere in an open space in the prototype and it highlights all the available links. These tools are available only on Mac computers, but similar tools are available under Windows.

Beyond this discussion, it’s not wise to try to cover software tools for making prototypes in this kind of textbook. The field is changing fast and whatever we could say here would be out of date by the time you read this. Plus, it wouldn’t be fair to the numerous other perfectly good tools that didn’t get cited. To get the latest on software tools for prototyping, it’s better to ask an experienced UX professional or to do your research online.

9.5.3 How to Build Wireframes?

Wireframes can be built using any drawing or word processing software package that supports creating and manipulating shapes, such as iWork Pages, Keynote, Microsoft PowerPoint, or Word. While such applications suffice for simple wireframing, we recommend tools designed specifically for this purpose, such as OmniGraffle (for Mac), Microsoft Visio (for PC), and Adobe InDesign.

Many tools and templates for making wireframes are used in combination—truly an invent-as-you-go approach serving the specific needs of prototyping. For example, some tools are available to combine the generic-looking placeholders in wireframes with more detailed mockups of some screens or parts of screens. In essence they allow you to add color, graphics, and real fonts, as well as representations of real content, to the wireframe scaffolding structure.

In early stages of design, during ideation and sketching, you started with thinking about the high-level conceptual design. It makes sense to start with that here, too, first by wireframing the design concept and then by going top down to address major parts of the concept. Identify the interaction conceptual design using boxes with labels, as shown in Figure 9-4.

Take each box and start fleshing out the design details. What are the different kinds of interaction needed to support each part of the design, and what kinds of widgets work best in each case? What are the best ways to lay them out? Think about relationships among the widgets and any data that need to go with them. Leverage design patterns, metaphors, and other ideas and concepts from the work domain ontology. Do not spend too much time with exact locations of these widgets or on their alignment yet. Such refinement will come in later iterations after all the key elements of the design are represented.

As you flesh out all the major areas in the design, be mindful of the information architecture on the screen. Make sure the wireframes convey that inherent information architecture. For example, do elements on the screen follow a logical information hierarchy? Are related elements on the screen positioned in such a way that those relationships are evident? Are content areas indented appropriately? Are margins and indents communicating the hierarchy of the content in the screen?

Next it is time to think about sequencing. If you are representing a workflow, start with the “wake-up” state for that workflow. Then make a wireframe representing the next state, for example, to show the result of a user action such as clicking on a button. In Figure 9-6 we showed what happens when a user clicks on the “Related information” expander widget. In Figure 9-7 we showed what happens if the user clicks on the “One-up” view switcher button.

Once you create the key screens to depict the workflow, it is time to review and refine each screen. Start by specifying all the options that go on the screen (even those not related to this workflow). For example, if you have a toolbar, what are all the options that go into that toolbar? What are all the buttons, view switchers, window controllers (e.g., scrollbars), and so on that need to go on the screen? At this time you are looking at scalability of your design. Is the design pattern and layout still working after you add all the widgets that need to go on this screen?

Think of cases when the windows or other container elements such as navigation bars in the design are resized or when different data elements that need to be supported are larger than shown in the wireframe. For example, in Figures 9-5 and 9-6, what must happen if the number of photo collections is greater than what fits in the default size of that container? Should the entire page scroll or should new scrollbars appear on the left-hand navigation bar alone? How about situations where the number of people identified in a collection are large? Should we show the first few (perhaps ones with most number of associated photos) with a “more” option, should we use an independent scrollbar for that pane, or should we scroll the entire page? You may want to make wireframes for such edge cases; remember they are less expensive and easier to do using boxes and lines than in code.

As you iterate your wireframes, refine them further, increasing the fidelity of the deck. Think about proportions, alignments, spacing, and so on for all the widgets. Refine the wording and language aspects of the design. Get the wireframe as close to the envisioned design as possible within the constraints of using boxes and lines.
