  • Publication number: 20210035557
    Abstract: A combination of propagation operations and learning algorithms is applied, using a selected set of labeled conversational logs retrieved from a subset of a plurality of conversational logs, to a remaining corpus of the plurality of conversational logs to train an automated response system according to an intent associated with each of the conversational logs. The combination of propagation operations and learning algorithms may include defining the labels by a user for the selected set of the subset of the plurality of conversational logs; training a probabilistic classifier using the defined labels of features of the selected set, wherein the probabilistic classifier produces labeling decisions for the subset of conversational logs; weighting the features of the selected set in a model optimization process; and/or training an additional classifier using the weighted features of the selected set and applying the additional classifier to the remaining corpus.

  • Patent number: 10885281
    Abstract: A mechanism is provided to implement a summarization mechanism for summarizing an identified natural language document using hyperbolic embeddings. Responsive to receiving a query from a user for a summarization of the identified natural language document, the summarization mechanism produces a hyperbolic embedding model of embeddings of the query. The summarization mechanism compares the embeddings of the query to each of a set of embeddings associated with a set of sentences of the identified natural language document. Responsive to identifying a subset of embeddings associated with the set of sentences of the identified natural language document having a semantic specificity to a subset of embeddings associated with the query, the summarization mechanism adds the sentence to a summary of the identified natural language document. The summarization mechanism then outputs the summary to the user.

  • Patent number: 10885082
    Abstract: A method overfits a word vector generating process to identify implicit relationships between two or more terms in a corpus. A server identifies instances of multiple user-generated pairs of terms in an original corpus of documents, in which the terms are labeled but a relationship between two or more of the corpus terms are not identified. The server then extracts sentences, from the original corpus of documents, that contain one or more of the multiple user-generated pairs of terms, and combines the sentences into a training corpus, which is used to purposely overfit a word embedding model. This word embedding model leads to a vector that is used to identify other terms that have a same type of relationship as that found in the multiple user-generated pairs of terms, such that search corpus of documents can be searched for similar terms that trained the word embedding model.

  • Patent number: 10769552
    Abstract: Mechanisms are provided for generating an answer to an input question. An input question is received and a set of candidate answers is generated along with, for each candidate answer in the set of candidate answers, a corresponding selection of one or more selected evidence portions from a corpus of information providing evidence in support of the candidate answer being a correct answer for the input question. The candidate answers are ranked based on an application of a justifying passage model (JPM) to the selected evidence portions for each of the candidate answers in the set of candidate answers. The JPM identifies whether a candidate answer is justified by a selected evidence passage corresponding to the candidate answer. A candidate answer is output as the correct answer for the input question based on the ranking of the candidate answers.

  • Patent number: 9560080
    Abstract: An information sharing paradigm for a cloud computing solution enables flexible organizational boundaries with respect to cloud resources. Cloud service customers manage their own organization boundary but can extend that boundary selectively by associating cloud resources they own with sets of domain names that may be associated with requests for cloud resources that the organization may be willing to share with other organizations that are using the cloud environment, and by ensuring that any such requests for resources that are shared in this manner are associated with one or more message handling policies that have been defined by (or otherwise associated with) the resource-owning organization. Cloud resources owned by an organization (even those marked as “internal only”) may be selectively shared with one or more other organizations using the cloud environment depending on the domain names associated with the requests. Message handling policies are enforced with respect to shared resources.

  • Patent number: 9515950
    Abstract: Mechanisms are provided for enabling collaboration across tenants in a multi-tenant environment using single sign-on (SSO) authentication/authorization. Various examples provide for creating a user account and provisioning a subscription to a user (e.g., to enable single sign-on authentication/authorization). The user is allowed to access services (e.g., collaborative services) in a multi-tenant environment by utilizing a subscription authorization of the user without prompting the user to authenticate by logging-in again (that is, without prompting the user to log-in again after the user has already logged-in and been authenticated for a given session). Other examples provide for mapping webspaces through URL hosts where each organization (that is, tenant) has its own set of namespace(s).
