A method for regulating the asking and motivating the answering of questions via a computer network. The number and complexity of questions asked is controlled by a question regulation method, and the number and quality of answers provided is controlled by an answer evaluation method. The question regulation method permits users to post more numerous or more complex questions based on factors such as viewing of advertising, or provision of marketing information. The answer measurement method may be used to reward those who supply numerous or high-quality answers with premiums, public recognition, or employment opportunities.

A system, method and computer program product for conducting questions and answers with deferred type evaluation based on any corpus of data. The method includes processing a query including waiting until a “Type” (i.e. a descriptor) is determined AND a candidate answer is provided; the Type is not required as part of a predetermined ontology but is only a lexical / grammatical item. Then, a search is conducted to look (search) for evidence that the candidate answer has the required LAT (e.g., as determined by a matching function that can leverage a parser, a semantic interpreter and / or a simple pattern matcher). In another embodiment, it may be attempted to match the LAT to a known Ontological Type and then look for a candidate answer up in an appropriate knowledge-base, database, and the like determined by that type. Then, all the evidence from all the different ways to determine that the candidate answer has the expected lexical answer type (LAT) is combined and one or more answers are delivered to a user.

A system and method for compensating users for responding to advertisements in an interactive manner poses questions for users and dynamically generates further questions in response to users' answers to previous questions. A user sets up an account on a remote computer that is then credited each time a user has completed the series of questions and answers relating to an advertisement. In setting up the account, the remote computer obtains demographic information from the user, such as the user's name, age, gender, place of residence and occupation. The remote computer can generate the questions not only in response to answers to previous questions but also in response to the demographic information. The remote computer provides the advertisers with the users' answers or with statistical information computed in response to the answers and the user demographics.

Faults and errors are diagnosed from a repository of directed graphs. Subsets of all the possible questions and answers in the fault diagnosis process are encoded as directed graphs. Downloading subsets from a repository to a remote user substantially reduces the number of transmissions between the user and the repository.

A query directed password scheme is disclosed that employs attack-resistant questions having answers that generally cannot be correlated with the user using online searching techniques, such as user opinions, trivial facts, or indirect facts. During an enrollment phase, the user is presented with a pool of questions from which the user must select a subset of such questions to answer. Information extraction techniques optionally ensure that the selected questions and answers cannot be correlated with the user. A security weight can optionally be assigned to each selected question. The selected questions should optionally meet predefined criteria for topic distribution. During a verification phase, the user is challenged with a random subset of the questions that the user has previously answered and answers these questions until a level of security for a given application is exceeded as measured by the number of correct questions out of the number of questions asked. Security may be further improved by combining the query directed password protocol with one or more additional factors such as Caller ID that assure that the questions are likely asked only to the registered user.

The invention relates to a deep learning-based question and answer matching method. The method comprises the following steps of: 1) sufficiently learning word orders and sentence local features of a question text and an answer text by utilizing two underlying deep neural networks: a long short-term memory network LSTM and a convolutional neural network CNN; and 2) selecting a keyword with best semantic matching on the basis of a pooling manner of an attention mechanism AM. Compared with existing methods, the method has the advantages of being in low in feature engineering workload, strong in cross-field performance and relatively high in correctness, and can be effectively applied to the fields of commercial intelligent customer service robots, automatic driving, internet medical treatment, online forum and community question answering.

A database collects questions and answers to the questions, each question having a plurality of answers. A question interface provides the questions to the database from various sources. An answer interface provides the answers to the database from various sources. A rating system assigns an accuracy rating to each of the plurality of answers for each question.

A knowledge-base system includes a processor, a database, and a matcher for matching questions of clients to answers in the database. The knowledge-base system can be administered by emails sent to the system. Question-answer entries can be added, deleted, and modified through the use of emails and / or other forms. The system can be accessed over a network or directly accessed with an administration computer. Questions and answers are separately indexed in the system to increase the accuracy of generated results. The generated response sent to the client can be modified based on the question asked, the results, and predefined templates. The system can also detect when the system receives a reply from a customer in response to sent results. Once a reply is detected, the email is forwarded to an alternate email address.
