  1. Fourth Workshop in Textual Case-Based Reasoning: Beyond Retrieval Workshop Co-chairs: Derek Bridge Paulo Gomes Nuno Seco

  2. Highlights • Definition of a new research problem: Conversational Textual CBR: how to automatically extract/organise the features that become prompts. • A new methodological framework: how to evaluate this kind of feature set. (Effectiveness, efficiency. A discussion about other criteria.) • A new application area: e-learning contents. Extracting features for use in solutions. Discussion of the influence of domain.

  3. Highlights • A system for report authoring which guides manual adaptation of similar reports retrieved from the case base. • A proposal that adaptation on structured cases can be followed by natural language generation. We discussed the practicalities of this. • In the context of adaptation, we compared • statistical approaches (e.g. vector space), • information extraction using expert rules, and • statistical approaches enhanced by learned knowledge.

  4. Highlights • A simple but effective visualisation of a case base where textual cases are represented by feature vectors. • An intriguing case base complexity measure: the degree to which sim. probs. have sim. solutions is assessed by the compressability of one of the visualisations. • A wide-ranging discussion of the role of maintenance in TCBR and in CBR in general: “it’s not (just) about deletion”.

  5. Highlights • Classification of sentences in incident reports as causes or facts using a novel vector representation: separate vectors characterise subject, verb and object. • Statistical techniques for recommending sentences to authors based on tools for, e.g., POS tagging, named entity extraction, construction of a translation model between problem and solution phrases... • Discussion considered the merits of challenges and competitions to furthering work in TCBR, with ref. to this challenge, to the cooking competition and to TREC.
