摘要： Systems and methods provided herein for a determining a meaning of an ambiguous term in a text segment based on a context term, a static knowledge graph and a temporal knowledge graph. These systems and methods access a first knowledge graph associated with the context term to determine a potential term that is the meaning of the unknown term. Upon determining that there are multiple potential terms in the first knowledge graph that could be the meaning of the unknown term, the systems and methods take into account the temporal dimension of relationships between entities for disambiguating the meaning of the unknown term. The systems and methods achieve this by determining a time stamp of the text segment and accessing a second knowledge graph associated with the first context term and related to the time stamp to determine the potential term that is the meaning of the first unknown term.

摘要： En la presente se describen sistemas y métodos que mantienen un contexto en sistemas de búsquedas de conversaciones. Una red neuronal artificial acepta consultas actuales y previas como entradas, y produce un valor que indica si la consulta previa y la consulta actual deberían someterse a una operación de combinación o a una operación de reemplazo para mantener una intención del usuario. Para realizar una operación de combinación, la consulta previa y la consulta actual se combinan para formar una consulta de búsqueda. Para realizar una operación de reemplazo, una porción de la consulta previa se reemplaza con una porción de la consulta actual.

摘要： The methods and systems described herein leveraging acoustic features of a user to generate and present a personalized content to a user. In one example, the method receives a voice query and determines that the query refers to either a first content item or a second content item. The first content item is associated with a first type assigned with a first score and the second content item is associated with a second entity type assigned with a second score. The method also determines whether the query is from the second entity type. The method ranks the first and the second content items based on this determination and generates for presentation of the first and the second content items based on the ranking. The method also changes the first or the second scores based on this determination and selects one of the first or the second content item for presentation.

摘要： Systems and methods are described to address shortcomings in a conventional conversation system via a novel technique utilizing artificial neural networks to train the conversation system whether or not to continue context. In some aspects, an interactive media guidance application determines a type of conversation continuity in a natural language conversation comprising first and second queries. The interactive media guidance application determines a first token in the first query and a second token in the second query. The interactive media guidance application identifies entity data for the first and second tokens. The interactive media guidance application retrieves, from a knowledge graph, graph connections between the entity data for the first and second tokens. The interactive media guidance application applies this data as inputs to an artificial neural network. The interactive media guidance application determines an output that indicates the type of conversation continuity between the first and second queries.

摘要： The system receives a voice query at an audio interface and converts the voice query to text. The system identifies entities included in the query based on comparison to an information graph, as well as dynamic types based on the structure and format of the query. The system can determine dynamic types by analyzing parts of speech, articles, parts of speech combinations, parts of speech order, influential features, and comparisons of these aspects to references. The system combines tags associated with the identified entities and tags associated with the dynamic types to generate query interpretations. The system compares the interpretations to reference templates, and selects among the query interpretations using predetermined criteria. A search query is generated based on the selected interpretation. The system retrieves content or associated identifiers, updates metadata, updates reference information, or a combination thereof. Accordingly, the system responds to queries that include non-static types.

摘要： Systems and methods provide a media guidance application that recognizes a plurality of natural language search queries for identifying a set of search results. For example, a user may want to determine when the Yankees are playing their next baseball game. The user may structure their query in multiple ways, such as, "When are the Yankees playing?" "What time is the Yankees game?" "When is the next Yankees baseball game?". The user would expect the same result, a description of when the Yankees are playing, regardless of how the query is structured. The systems and methods enable a user to use a plurality of search queries when searching for items or information to get desired results.

摘要： The present invention relates to a method for determining whether a portion of a 5 current query should be merged or replaced with a portion of a previous query. The method comprises generating a neural network that takes a previous query and a current query as input and outputs a result indicating a merge or replace operation. The method further comprises receiving a first query and a second query, wherein the first query is received prior to receiving the second query. Further, the method 10 comprises mapping the first query and the second query to the previous query and current query inputs of the neural network. Using the neural network, the method determines whether the first query and the second query are associated with a result indicating a merge or replace operation. In response to determining that the first query and the second query are associated with a result indicating a merge 15 operation, the method involves merging the first query and the second query. In response to determining that the first query and the second query are associated with a result indicating a replace operation, the method involves: selecting a first portion of the first query and a second portion of the second query that correspond to each other; and replacing the first portion of the first query with the second 20 portion of the second query.
