According to an aspect, automatically linking text to concepts in a knowledge base using differential analysis includes receiving a text string and selecting, based on contents of the text string, a plurality of data sources that correspond to concepts in the knowledge base. In a further aspect, automatically linking the text to the concepts includes calculating, for each of the selected data sources, a probability that the text string is output by a language model built using the selected data source, calculating a probability that the text string is output by a generic language model, calculating link confidence scores for each concept based on a differential analysis of the probabilities, and creating a link from the text string to one of the concepts in the knowledge base. The creating is based on a link confidence score of the concept being more than a threshold value away from a prescribed threshold.

Solid-state storage management for a system, the management including establishing, externally to a solid-state storage board, a correspondence between a first logical address and a first physical address on solid-state storage devices located on the solid-state storage board. The solid-state storage devices include a plurality of physical memory locations identified by physical addresses. The correspondence between the first logical address and the first physical address is accepted by the solid-state storage board. The correspondence between the first logical address and the first physical address is stored in a location on a solid-state memory device that is accessible by an address translator module, the address translator module and the solid-state memory device located on the solid-state storage board. The first logical address is translated to the first physical address by the address translator module based on the previously established correspondence between the first logical address and the first physical address.

According to an aspect, conceptual analysis of a document includes accessing a concept graph that includes a plurality of nodes and edges. Each node represents a concept and each edge represents a known relation between two concepts. Conceptual analysis of the document further includes computing a relevance of the document to concepts in the concept graph. The computing includes receiving a priori information about the document including concepts extracted from the document. The concepts extracted from the document include a subset of the concepts in the concept graph. The computing also includes combining the a priori information and the concept graph to generate a posteriori information that indicates a likelihood that the document is related to each of the concepts in the concept graph.

A method and apparatus are provided for recommending concepts from a first concept set in response to user selection of a first concept Ci by performing a natural language processing (NLP) analysis comparison of the vector representations of a first concept set of candidate concepts and a second concept set of user-explored concepts to determine a similarity measure corresponding to each candidate concept, and to select therefrom one or more of the candidate concepts for display as recommended concepts which are related to the one or more user-explored concepts from the navigation history for the user based on the similarity measure for each candidate concept.

A method and apparatus are provided for recommending concepts from a first concept set in response to user selection of a first concept Ci by performing a natural language processing (NLP) analysis comparison of vector representations of user concepts contained in written content authored by the user and candidate concepts in a first concept set to determine a similarity measure for each candidate concept, and to select therefrom one or more of the candidate concepts for display as recommended concepts which are related to the user concepts contained in written content authored by the user based on the similarity measure between each candidate concept and each user concept.

Mechanisms are provided for performing a matrix operation. A processor of a data processing system is configured to perform cluster-based matrix reordering of an input matrix. An input matrix, which comprises nodes associated with elements of the matrix, is received. The nodes are clustered into clusters based on numbers of connections with other nodes within and between the clusters, and the clusters are ordered by minimizing a total length of cross cluster connections between nodes of the clusters, to thereby generate a reordered matrix. A lookup table is generated identifying new locations of nodes of the input matrix, in the reordered matrix. A matrix operation is then performed based on the reordered matrix and the lookup table.

Embodiments relate to estimating closeness of topics based on graph analytics. A graph that includes a plurality of nodes and edges is accessed. Each node in the graph represents a topic and each edge represents a known association between two topics. A statistical traversal experiment is performed on the graph. A strength of relations between any two topics represented by nodes in the graph is inferred based on statistics extracted from the statistical traversal experiment.

A method includes comparing a number of memory blocks in a first pool of free memory blocks in a memory to a threshold. The memory includes memory blocks that are logically divided into the first pool, a second pool, and a third pool of memory blocks. The first pool of free memory blocks is expanded based on determining that the number of memory blocks in the first pool of free memory blocks is less than the threshold. The expanding includes: selecting a first memory block from the second pool of memory blocks, the first memory block comprising active and non-active content; selecting a second memory block from the third pool of memory blocks; copying the active content of the first memory block to the second memory block; erasing the first memory block; and adding the first memory block to the first pool of free memory blocks.

摘要:
According to an aspect, searching, recommending, and exploring documents through conceptual associations includes receiving a plurality of documents and extracting concepts from each of the documents. A degree of relation between each of the documents and concepts in a knowledge base is calculated. An aspect also includes, in response to receiving a query, determining one or more concepts from the query. For each of the concepts, a list of documents having a highest degree of relation to the concept is retrieved. An aspect also includes outputting a list that is responsive to the one or more retrieved lists.
