Abstract: A deduplication system and method involves interaction between a software-based system that manages the overall background deduplication process and a hardware-based system that includes a hardware-based filesystem manager and a hash generator. A filesystem checkpoint mechanism is leveraged to manage the background deduplication process and also to reduce processing complexity with respect to identifying chunks that are candidates for deduplication and processing such chunks.

Abstract: A method for extracting a relations graph uses an ontology graph in which nodes represent entity classes or concepts and edges represent properties of the classes. A property is associated with a constraint which defines a range of values that can be taken without incurring a cost. Input text in which entity and concept mentions are identified is received. An optimal set of alignments between a subgraph of the ontology graph and the identified mentions is identified by optimizing a function of constraint costs incurred by the alignments and a distance measure computed over the set of alignments. The relations graph is generated, based on the optimal set of alignments. The relations graph represents a linked set of relations instantiating a subgraph of the ontology. The relations graph can include relations involving implicit mentions corresponding to subgraph nodes that are not aligned to any of the concept or entity mentions.

Abstract: Knowledge representation in a multi-layered database includes systems and methods for storing and retrieving data in the multi-layered database. The multi-layered database includes an object database layer that stores objects corresponding to real world entities and each object is associated with object properties, object relationships, and relationship properties. Underlying the object database layer is a graph database layer that stores nodes, node properties associated with the nodes, edges, and edge properties associated with the edges, wherein the nodes correspond to objects, node properties are indicative of the object properties, the edges are indicative of the object relationships, and the edge properties are indicative of the relationship properties of the object. Further, underlying the graph database layer is a backend database layer that stores corresponding data and metadata. Data can be stored and retrieved from the multi-layered database by composing and decomposing information between layers.

Abstract: Multi-dimensional aggregation using user interface workflow composition is described. A determination is made whether aggregation is complete for each level of a multi-dimension aggregation. Data is retrieved for a level of aggregation in response to a determination that aggregation is not complete for each level of the multi-dimension aggregation. The data is aggregating based on the level of aggregation. The aggregated data is stored for a next level of aggregation. The data for a final level of aggregation is output to a user interface in response to a determination that aggregation is complete for each level of the multi-dimension aggregation.

Abstract: Systems and methods are described herein for efficiently providing personalized search results to a user. Personalized search allows a user to receive search results that are most relevant to that user. For example, when a user with a strong interest in rap searches for “50 cent” they may be presented with top search results corresponding to 50 Cent's rap albums. Conversely, when a coin collector searches for “50 cent” they may be presented with top search results containing antique coins.

Abstract: Systems and methods for automating the retrieval of partitionable search results from a database and reducing the latency of delivering the partitionable search results are disclosed. A query for searching a database is constructed. Multiple processing tasks are assigned and executed to retrieve partitioned search results from a database in parallel. Each partition of search results is returned to the user as response messages. Response messages may be continuously received until all search results responsive to the query have been retrieved from the database. When multiple processing tasks are used to retrieve and deliver partitioned search results in parallel, server, internet and client resources are optimized, and the throughput of search results and metadata are increased, and the process of narrowing or filtering search results is an interactive and informed process for the user.

Abstract: A “Poll Optimizer” provides automated techniques for performing various combinations of both static and runtime optimizations for crowd-sourced queries including, but not limited to, crowd-sourced opinion-based polls. These optimizations have been observed to improve poll performance by reducing factors such as completion times, monetary costs, and error rates of polls. In various implementations, the Poll Optimizer receives an input query representing a crowd-sourced poll that is formatted as a multi-layer structure (e.g., LINQ-based queries natively supported by .NET languages, JQL-based queries supported by JAVA, etc.). The Poll optimizer then iteratively reduces the multi-layer structure of the input query to construct a reformulated query. This reformulated query is then matched to an optimized execution process selected from a plurality of predefined execution processes.

Abstract: Methods and apparatus for modifying a user profile for a recommendation algorithm are provided. A user is provided with electronic access to an item. The item may comprise one of a document, an article, a chart, a graphic, a report, a web page, or the like. User interaction with the item is enabled. The user interaction with the item is then electronically tracked and stored. The user's user profile used by a recommendation engine is then modified based on the tracked user interactions. The user interaction may comprise at least one of annotating, highlighting, modifying, customizing, adding comments to the item, and the like. The user modified item can be saved and details of the user interaction with the item may be used to modify the user profile. At least one of items or peer recommendations can then be provided to the user based on the modified user profile.

Abstract: Methods and systems for determining one most specific row within a database table. An index includes an index structure for each column of the database table. Each index structure includes an array of pointer tuples for each value occurring in the column and a bitmap indicating cells without values. A first pointer of the tuple indicates a value and a second pointer indicates the row of the database table with the value. The index also indicates an order of specificity of the rows of the database table. A computer system processes a request by using the bitmaps of the index structures to maintain all rows of the database table without values and the pointer tuples to filter all rows of the database table that do not include the respective input value. The one row being highest in the order of specificity from the remaining rows is selected and returned.

Abstract: Embodiments of the present invention disclose a method, a computer program product, and a computer system for identifying information gaps in corpora. A computer receives a document and extracts keywords from the document while filtering trivial keywords. The computer identifies and extracts top keywords detailed by the document using a topic modelling approach before determining whether the extracted top keywords exceed a threshold use frequency. Based on determining that the top keywords exceed a threshold use frequency, determining whether the top keywords have a relation to other entities within the document and, if so, determining whether the top keywords are defined within the document. Based on determining that the top keywords are not defined in the document, adding the top keywords to a list and defining the top keywords.

Abstract: In one embodiment, a new file creation cache is reserved on a fast storage device that is part of a composite storage device that also includes a slow storage device; the composite storage device is treated as a single logical volume (or a plurality of logical volumes) by a file system which maintains a mapping table that is used to determine whether the write operation is for a new file. If the write operation is for a new file, the file system attempts to write the new file to the fast storage device. If the write operation is not for a new file, the mapping table specifies which device is used for the write operation.
