The BankXX system models the process of perusing and gathering information for argument as a heuristic best-first search for relevant cases, theories, and other domain-specific information. As BankXX searches its heterogeneous and highly interconnected network of domain knowledge, information is incrementally analyzed and amalgamated into a dozen desirable ingredients for argument (called argument pieces), such as citations to cases, applications of legal theories, and references to prototypical factual scenarios. At the conclusion of the search, BankXX outputs the set of argument (...) pieces filled with harvested material relevant to the input problem situation.This research explores the appropriateness of the search paradigm as a framework for harvesting and mining information needed to make legal arguments. In this article, we describe how legal research fits the heuristic search framework and detail how this model is used in BankXX. We describe the BankXX program with emphasis on its representation of legal knowledge and legal argument. We describe the heuristic search mechanism and evaluation functions that drive the program. We give an extended example of the processing of BankXX on the facts of an actual legal case in BankXX's application domain — the good faith question of Chapter 13 personal bankruptcy law. We discuss closely related research on legal knowledge representation and retrieval and the use of search for case retrieval or tasks related to argument creation. Finally we review what we believe are the contributions of this research to the understanding of the diverse disciplines it addresses. (shrink)

The narratives studied by schema-based models or story grammars are generally simpler than those found in literary texts, such as short stones or novels. Literary narratives are indeterminate, exhibiting conflicts between schemata and frequent ambiguities in the status of narrative elements. An account of the process of comprehending such complex narratives is beyond the reach of purely cognitive models. It is argued that during comprehension response is controlled by affect, which directs the creation of schemata more adequate to the text. (...) Several properties of affect that make it appropriate for this model of narrative are discussed. A short story by Virginia Woolf is analysed in the light of the proposed model. A study with readers of the story is described, which illustrates the process of schema formation: Shifts in the relative importance of story phrases across the reading and the comments made by readers point to a process of schema creation under the control of affect. It is argued that affect may play a more productive role in cognitive processes than is generally acknowledged. (shrink)

The present paper is meant to summarise and enlighten the theoretical implications of the twin theories of text comprehension and of text compression. Compatibility and non-exclusiveness of particle-like analysis of language and wave-like analysis of intentionality are also demonstrated within the newly established quantum linguistics framework. The informative state of language is viewed as being relatively stable; once activated and subject to motion, therefore reaching a communicative state, different phenomena occur, which may be observed, analysed and visualised through CPP-TRS observational (...) devices. Relativity theory may therefore be organised in terms of quanta with continuity and no contradiction. (shrink)

Three experimental tasks—spontaneous telling of a story, reading, and parsing the story—were used to determine whether empirical data reflect the narrative structure of stories and can be predicted by a plot unit analysis of the stories (Lehnert, 1981). It was found that spontaneous pause durations at sentence breaks were highly correlated with the importance of these breaks as predicted theoretically. Only low correlations were obtained, however, when reading pause durations were correlated with the model. As for parsing values, the value (...) of the correlation coefficients depended on whether stories had sufficient superficial linguistic cues to help the subjects in parsing. It was concluded that spontaneous pausing not only reflects the narrative structure of stories, but can be used as a guide to constructing theories of narrative structure as well as for deciding between competing theories.
