    1. Syntactic parser assisted semantic rule inference

      Natural language understanding (NLU) engines perform better when they are trained with large amounts of data. However, a large amount of data is not always available. Embodiments of the present invention overcome this problem by generating annotated data for use in a NLU system. An example embodiment generates annotated data by parsing an input annotated phrase, generating a syntactic tree reflecting a grammatical structure of the parsed phrase, and generating one or more alternative versions of the input annotated phrase based on the syntactic tree. Alignment between expressions and corresponding annotations in the annotated phrase are preserved in the one ...

    2. System and method for semantic processing of natural language commands

      A system, method and computer-readable storage devices are for processing natural language commands, such as commands to a robotic arm, using a Tag & Parse approach to semantic parsing. The system first assigns semantic tags to each word in a sentence and then parses the tag sequence into a semantic tree. The system can use statistical approach for tagging, parsing, and reference resolution. Each stage can produce multiple hypotheses, which are re-ranked using spatial validation. Then the system selects a most likely hypothesis after spatial validation, and generates or outputs a command. In the case of a robotic arm, the command ...

    3. Serving recurrent calendar events

      Computer-implemented systems and methods are provided for indexing and serving calendar event information. In accordance with some embodiments, information common to, and unique among, instances of a recurrent event may be determined. A markup document and search document including the common information and unique information may be generated, and a search index may be updated. Also, in accordance with some embodiments, a search query may be received and parsed, and recurrent event information can be scored as a possible search result.

    4. Optimizing parsing outcomes of documents

      A mechanism is provided for optimizing parsing of grammatical prose in a multi-prose electronic document. A received multi-prose electronic document is partitioned into a set of text segments of homogenous prose. A set of predefined Natural Language (NL) parsers is executed on each text segment in order to discern and measure a quality of parses by each NL parser throughout the multi-prose electronic document. A cross-parse analysis of the multi-prose electronic document and an aggregation of adjacent clauses or sentences of poor quality parses are performed. For each text segment, aggregation patterns yielding a best semantic role match are identified ...

    5. Method and apparatus for providing an anti-bullying service

      An approach is provided for an anti-bullying service. A service platform monitors interaction data from one or more applications, wherein the interaction data is associated with an interaction between a source and a target. The service platform analyzes the interaction data to parse one or more indicators of a monitored conduct between the source and the target. The service platform then initiates at least one of (a) a recording of the interaction data; (b) a transmission of an alert message, the one or more indicators, the interaction data, the monitored conduct, or a combination thereof to a third party; and ...

    6. Feature-based autocorrection

      A computing device is described that outputs for display at a presence-sensitive screen, a graphical keyboard having keys. The computing device receives an indication of a selection of one or more of the keys. Based on the selection the computing device determines a character string from which the computing device determines one or more candidate words. Based at least in part on the candidate words and a plurality of features, the computing device determines a spelling probability that the character string represents an incorrect spelling of at least one candidate word. The plurality of features includes a spatial model probability ...

    7. Token-level interpolation for class-based language models

      Optimized language models are provided for in-domain applications through an iterative, joint-modeling approach that interpolates a language model (LM) from a number of component LMs according to interpolation weights optimized for a target domain. The component LMs may include class-based LMs, and the interpolation may be context-specific or context-independent. Through iterative processes, the component LMs may be interpolated and used to express training material as alternative representations or parses of tokens. Posterior probabilities may be determined for these parses and used for determining new (or updated) interpolation weights for the LM components, such that a combination or interpolation of component ...

    8. Domain specific language design

      A computing system includes a processor; and a memory communicatively coupled to the processor. The processor is configured to: receive from a user, a number of annotations for at least one of a set of statements within a problem domain, the annotations identifying a set of elements within the statement; form a set of grammar rules for the problem domain based on the annotations; and parse the set of statements using the set of grammar rules.

    10. Natural language processing utilizing transaction based knowledge representation

      Mechanisms are provided for processing logical relationships in natural language content. A logical parse of a first parse of the natural language content is generated by identifying latent logical terms within the first parse indicative of logical relationships between elements of the natural language content. The logical parse comprises nodes and edges linking nodes. At least one knowledge value is associated with each node in the logical parse. The at least one knowledge value associated with at least a subset of the nodes in the logical parse is propagated to one or more other nodes in the logical parse based ...

    12. Natural language processing utilizing logical tree structures

      Mechanisms are provided for processing logical relationships in natural language content. Natural language content is received, upon which a reasoning operation is to be performed. A first parse representation of the natural language content is generated, by a parser, by performing natural language processing on the natural language content. A logical parse of the first parse is generated by identifying latent logical operators within the first parse indicative of logical relationships between elements of the natural language content. A reasoning operation on the logical parse is executed to generate a knowledge output indicative of knowledge associated with one or more ...
