Relevance feedback is an automatic process, introduced over 20 years ago, designed to produce improved query formulations following an initial retrieval operation. The principal relevance feedback methods described over the years are examined briefly, and evaluation data are included to demonstrate the effectiveness of the various methods. Prescriptions are given for conducting text retrieval o...

Abstract: For this year our team participated in the medical image retrieval task. Most of our effort was invested in processing the collection using Metamap to assign Unified Medical Language System (UMLS) concepts to each of the images that included some associated text. This process generated metadata that was added to each image and included the UMLS concept number as well as the primary te...

Focusing on the document structure of patent, two search databases AC and WH were built and compared in retrieval performance, where AC includes only abstract and claim sections in patent and WH includes the whole patent texts. Moreover, we attempted to combine search results for the two databases to improve retrieval performance. Another point of our experiments is cross-lingual patent retriev...

When we talk about felt experiences, such as physical pains and pleasures, we normally expect our conversational partners to provide empathetic feedback of some kind. Some models of human interaction predict that this feedback should be similar in form to our original production; the gestures, expressions and other non-verbal signals we use to explain our experience should be mirrored in the em...

Current case acquisition and case base maintenance techniques implement quality assurance for cases through reviews or by analyzing case properties before making a case available for retrieval. Since reviews of cases with much textual data, in particular, cannot be fully automated, this is done by a maintenance team. With limited resources, this maintenance team becomes a bottleneck. To reduce ...

some literary texts seem being created on the threshold of two different movements, since they reflect the features of them both. some literary features are also common in two different literary movements and they can even be seen in the works belong to two different eras. the novel “asfār-e-kātebān” (books of scribers) is among the works which have lots of techniques and measures which are the...

We present here some transmedia similarity measures that we recently designed by adopting some “intermediate level” fusion approaches. The main idea is to use some principles coming from pseudorelevance feedback and, more specifically, transmedia pseudo-relevance feedback for enriching the mono-media representation of an object with features coming from the other media. One issue that arises wh...

Our participation to ImageCLEFphoto07, for the first time, was motivated by assessing several transmedia similarity measures that we recently designed and developed. The object of investigation consists here in some “intermediate level” fusion approaches, where we use some principles coming from pseudo-relevance feedback and, more specifically, use transmedia pseudo-relevance feedback for enric...

This is our first participation in the ciQA task. Instead of exploring conversation strategies in question answering [3, 4], we decided to focus on simple interaction strategies using relevance feedback. In our view, the ciQA task is not designed to evaluate user initiative interaction strategies. Since NIST assessors act as users, the motivation to take an initiative is lacking. It is not clea...
