چکیده
It's now time to go back to the user We have detailed a lot of tools and techniques that allow for sophisticated matching criteria to be applied, however in doing so we have implicitly assumed that the user " knows " how to formulate her queries/preferences In some cases the user does not know at all what to look for. In this case, a " browsing " activity should be supported. We do not consider browsing in the following Although with traditional DB's and a few attributes this might be a reasonable assumption, when we consider many attributes/features it is not clear how a user might guess the right combination of weights How can you define the 64 weights of a color-based search using the weighted Euclidean distance? A solution could be to resort to qualitative preferences (e.g., Skyline), however even in such scenario we might want to further refine our notion of " best match " (e.g., using ranked skyline queries)…

Query expansion based on relevance feedback and latent semantic analysis
Web search engines are one of the most popular tools on the Internet which are widely-used by expert and novice users. Constructing an adequate query which represents the best specification of users’ information need to the search engine is an important concern of web users. Query expansion is a way to reduce this concern and increase user satisfaction. In this paper, a new method of query expa...

متن کاملStatistical Machine Translation Models for Personalized Search
Web search personalization has been well studied in the recent few years. Relevance feedback has been used in various ways to improve relevance of search results. In this paper, we propose a novel usage of relevance feedback to effectively model the process of query formulation and better characterize how a user relates his query to the document that he intends to retrieve using a noisy channel...

Content-based image retrieval (CBIR) has received considerable research interest in the recent years. The basic problem in CBIR is the semantic gap between the high-level image semantics and the low-level image features. Region-based image retrieval and learning from user interaction through relevance feedback are two main approaches to solving this problem. Recently, the research in integra...
متن کاملA Log-Based 3D Model Retrieval Relevance Feedback Scheme Using Biased SVMs
Retrieval relevance feedback is an iterative search technique to bridge the semantic gap between the high level user intention and low level data representation. This technique interactively determines a user's desired output or query concept by asking the user whether certain proposed 3D models are relevant or not. In the past, most research efforts in 3D model retrieval field have focused on ...
