Semantic reranking

Highlighted concept reranking is a simple and quick reranking approach used to highlight particular characteristics in a semantic query figure 2 a emphasizes the concept outdoor in the query a person playing guitar outdoors. Specific semantic signatures significantly improve both the accuracy and efficiency of image re-ranking the original visual features of thousands of dimensions can be projected to the semantic. Abstract: image search reranking has become a widely-used approach to significantly boost retrieval performance in the state-of-art content-based image retrieval system most of the methods merely rely on matching visual distances between query and initial results or among initial results to detect. An attribute-assisted reranking model for web image search junjie cai, zheng-jun zha, member, ieee, meng wang, shiliang zhang, and qi tian, senior member, ieee abstract—image search reranking is an effective approach. Content-based image retrieval (cbir), also known as query by image content and content-based visual information retrieval (cbvir) is the application of computer vision techniques to the image retrieval problem, that is, the problem of searching for digital images in large databases (see this survey for a recent scientific overview of the cbir field.

Web image re-ranking using query-specific semantic signatures 1 web image re-ranking using query-specific semantic signatures abstract: image re-ranking, as an effective way to improve the results of web-based image search, has been adopted by current commercial search engines such as bing and google. Lution (sec 3), as well as our unofcial semantic re-ranker (sec 4) since the shared task's main goal is to enable a discussion of the challenges of. Abstract this paper proposes a word embedding-based reranking algorithm with a boosting the algorithm converts queries and documents into sets of word embeddings represented by vectors and reranks documents according to a similarity defined with the word embeddings as in latent semantic indexing (lsi) and supervised semantic indexing (ssi. Image reranking using semantic signatures mschanusha, mrksivareddy abstract: image re-ranking, as an effective way to.

Search reranking is defined as reordering visual documents such as images or video clips based on the initial search results or the auxiliary knowledge to improve the search. Semantic parsing, in the form of sequential segmentation and labeling, makes it easy to convert spoken and typed questions such as cheap lebanese restaurants in doha with take out into database queries. Semantic signatures of the images are acquired by projecting their visual features into their related semantic spaces and these semantic signatures are compacted using hashing techniques.

The semantic signatures are of 25 dimensions on average the total cost linearly increases with the number of query keywords, which can be processed in parallel. Semantic re-ranking in ad-hoc robust retrieval 3 topics to evaluate the performance we executed several runs using the topics provided in each track. A semantic re-ranking module re-ranks the nlu-ranked semantic interpretations based on at least one of dialogue context information and world knowledge information a dialogue manager responds to the re-ranked semantic interpretations and generates the output prompts so as to manage a dialogue process with the human user.

Utilization of co-occurrencerelationships between semantic concepts in re-ranking for information retrieval chao chen, lin lin and mei-ling shyu. Logical and semantic features we propose an approximated joint decoding method by reranking the n-best segmenter out- reranking method is very effective we achieved. Recently people proposed to match images in a semantic space which used attributes or reference classes closely related to the semantic meanings of images as basis.

In this paper, we extensively study the use of syntactic and semantic structures obtained with shallow and deeper syntactic parsers in the answer passage reranking task. Remaining images in the semantic space are re-ranked based on their visual similarities with the query image the visual features of images and the word image index file are pre-computed offline and stored1 the main online computational cost is on comparing visual features. Supervised parser domain adaptation in semantic role labeling, a task in which parsing accuracy is without reranking is effective when the manually annotated.

In proceedings of the coling/acl-2006 main conference poster sessions pp 263-270, sydney, australia, july 2006 discriminative reranking for semantic parsing ruifang ge raymond j mooney. Criminative reranking: (a) we studied a semantic inconsistency met- ric that can be applied to slu hypotheses to select those that are more likely to be correct (b) we apply a model selection. Semantic retrieval process to realize semantically equivalent terms in documents and query terms using word net by associating such terms using semantic similarity methods. 1 web image re-ranking using query-specific semantic signatures xiaogang wang, member, ieee, shi qiu, ke liu, and xiaoou tang, fellow, ieee abstract—image re-ranking, as an effective way to improve the results of web-based image search, has been adopted by current.
