Semantic Matching in Search
In this talk, we will give a high level introduction to our book entitled “Semantic Matching in Search”, which was published recently in Foundations and Trends in Information Retrieval [1]. We will start our talk by pointing out the importance of semantic matching for natural language processing and information retrieval. Most of the tasks in natural language processing and information retrieva...
متن کاملAn Improved Semantic Schema Matching Approach
Schema matching is a critical step in many applications, such as data warehouse loading, Online Analytical Process (OLAP), Data mining, semantic web [2] and schema integration. This task is defined for finding the semantic correspondences between elements of two schemas. Recently, schema matching has found considerable interest in both research and practice. In this paper, we present a new impr...
متن کاملA Semantic Search Algorithm for Ontology Matching
Most of the ontology alignment tools use terminological techniques as the initial step and then apply the structural techniques to refine the results. Since each terminological similarity measure considers some features of similarity, ontology alignment systems require exploiting different measures. While a great deal of effort has been devoted to developing various terminological similarity me...
متن کاملIncorporating Semantic Knowledge into Latent Matching Model in Search
The relevance between a query and a document in search can be represented as matching degree between the two objects. Latent space models have been proven to be effective for the task, which are often trained with click-through data. One technical challenge with the approach is that it is hard to train a model for tail queries and tail documents for which there are not enough clicks. In this pa...
متن کاملEnabling semantic search for EO products: an ontology matching approach
Access to Earth Observation (EO) products remains difficult for end-users. To address this, we developed the Prod-Trees platform[2], a semantically enabled search engine for EO products. Users guide their search through a number of ontologies related to EO domain. To facilitate users in finding terms that fit better to their needs, we created mappings between these ontologies. In this paper, we...
