Detecting Deception in Civil and Criminal Narratives*

The talk will consider the reliability of using linguistic cues to identify deceptive and non-
deceptive regions in “real world” narratives — criminal statements, police interrogations
and legal testimony. To test the accuracy of these cues in predicting deception, we tagged
the narratives for 12 language-based deception cues as well as for the truth value of all
propositions that could be externally verified as true or false. A measure of the density of
cues was then calculated, with high cue density taken to identify a passage as deceptive.
This method was 74.9% accurate in predicting True/False on the externally verified
propositions, as compared to the baselines that range from 50-57%. This preliminary
result suggests that linguistic cues can provide a reasonable guide to the sectioning of
narratives into deceptive and non-deceptive statements.

Although the academic analysis of suicide-related communications often centers on attempting to identify indicators of victim intent (e.g. actual suicide vs. “cry for help”), it is more important to first determine whether such communications were indeed authored by the victim or whether the apparent suicide and related communications were staged in an attempt to cover up a murder or attempted murder. Hence, alleged written suicide communications should never be assessed in isolation but rather in comparison with known writings of the victim and, if the investigation dictates, with the known writings of others who may be suspects in the authorship of the communication and/or the actual death.

In 2007, three separate homicides/homicide attempts in Pennsylvania, New York, and Virginia were initially handled as suicides, as each crime scene included an alleged suicide communication. However, in each case factors emerged that suggested homicide (and, in one case, attempted homicide). In each case, forensic linguistic comparison of the alleged suicide communication with documents known to be authored by the victim and by suspected perpetrators yielded invaluable evidence indicative of inconsistency of the “suicide” notes with the victims’ known writings and/or consistency with those of the suspects. Each case resulted in an arrest for the charge of homicide and the eventual successful conviction of each.

In this presentation, I will outline the forensic linguistic analyses conducted in connection with these cases, demonstrating the efficacy of qualitative and quantitative forensic stylistic methods of authorial attribution focusing on such features as punctuation, orthography and lexical usages. I will highlight linkages between forensic stylistics and sociolinguistic studies of stylistic variation and authorial imitation, as well as recent computational linguistic methods in authorial attribution of computer mediated communications, thereby demonstrating the solid linguistic basis as well as practical utility of the authorial attribution methods used in these three cases.

Global Education: Hope or Hype?

A buzz is going around in U.S. undergraduate education — the buzz of “global awareness/perspectives/literacy/proficiencies” etc. For some, it encapsulates the essence of a liberal arts education for the 21st century, for others it represents a sloppy use of language or straightforward gibberish. From a more dispassionate point of view, the discussion about the advantages or disadvantages of a global education can be seen as an indication for a widespread uncertainty how to best prepare students for a successful life as professionals and citizens in an increasingly interconnected world. In his talk, Jochen Fried will focus not so much on specific models of, or approaches to, global education. Instead, he will analyze some of the the discourse patterns which underpin this call for a reorientation of what constitutes a meaningful and relevant education for an age of mounting complexity and uncertainty.

A Dozen Headaches for Dictionary Advocates In the 21st Century

Lexicography is often reducible to cycling units of information, especially words. It is usually done, especially in what is often called commercial lexicography, with an eye on the clock. Budgets for dictionary projects are usually quite restricting. One consequence of such confinement is the headache of complying with production schedules, often imposed by a publisher. This brief presentation will focus on what such headaches entail and whether or not there is a suitable cure: (1) One of the most important challenges for present-day dictionary editors is the large numbers which accompany collections of evidence. (2) “Where do all the new words come from?” (3) Print, electronic, and Web-based, each have attractors and detractors—what to do? (4) “Doomed-ness” of unabridged dictionaries—reality or dreaming. These four problem areas are of interest but probably not of overwhelming importance to teachers and students. Their headaches include: (5) Why is it here and not there? (6) Why is it neither here nor there? (7) How do I get my students to read the “blankity-blank” front matter? These half-dozen or so issues and more will be discussed; there’s room for your headaches, too.
