## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present patent application claims the priority benefit of U.S. provisional patent application 62/731,753 filed Sep. 14, 2018, the disclosure of which is incorporated by reference herein.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to file management. In particular, the present invention relates to managing sources and digital citations within a trusted storage repository.
2. Description of the Related Art
There are myriad sources of information, and it is often challenging to verify a source or reference that is brought up in discussion. Further, because digital sources may often be updated or edited after the fact, there is no guarantee that a source referenced for support at one point in time will continue to support the same argument or position at a later point. Further, it is difficult and impractical to audit a referenced source for authenticity, support or dispute of the source, changes to the source over time, and other historical and/or contextual elements to a source which impact its value and/or relevance (e.g., acceptance within a community or by particular persons, consistency with other sources, credibility of the source and/or those supporting or disputing it, context of the source, etc.) to its referencing counterpart. In particular, as technologies and opportunities to manufacture fake content (e.g., falsified sources, fake facts, etc.) have increased, the number of evidence properties that can be examined has also increased such as evidence types, degrees, and interrelationships.
It is with these observations in mind, among others, that aspects of the present disclosure were concerned and developed.

DETAILED DESCRIPTION
Embodiments of the present invention may include systems and methods for fact management. Such system may include a storage repository may hold evidence data that includes citable, digital information. Further, an evidence certification process may be executed to determine veracity of the evidence data. Meanwhile, a credentialing process may be executed to record a history associated with the evidence data. Such history may include a history of one or more users. A source monitoring process may be executed to detect historical changes to evidence data, which may be recorded by the credentialing process
Aspects of the present disclosure involve systems for managing facts and, in particular, sources, citations, and other fact references or discrete premises. In one example, a system may manage any data that can be sourced and/or cited digitally by providing user-based credentialing, certification, and navigation of sources. In particular, a flexible data store can store facts and/or argument structures composed of sources and digital citations.
In some examples, an evidence certification system can be linked to the flexible data store in order to provide curated, citable references for use in debate, discussion, and other forms of dialogue. Such citable references may be associated with a source that has been previously approved (e.g., by one or more curators). In particular, facts and sources can be managed in a cooperative and distributed fashion to allow for efficient auditing of an immutable historical record for a source and its content throughout the publication lifecycle. Facts and sources can be verified at multiple levels of abstraction and the content verification can be performed by various subsystems and processes. As a result, time taken for validating or fact checking premises and sources can be reduced and new avenues of rhetoric analysis and the like can be explored. Further, smart contracts and the like can be used to provide automated source disclosure at a highly granular level directly within the immutable historical record. Said another way, just as logistic and sourcing processes can be recorded and audited by an immutable historical record (e.g., a blockchain), so too can premises, ideas, and facts.
Certified evidence (e.g., facts, premises, and other digital fact elements, etc.) can be provided for use as various kinds of support and for various citation formats. Certifying evidence may include multiple content verification processes (discussed below) for providing assurance that a piece of evidence is what it purports to be. Importance rankings can be assigned to evidence by the evidence certification system for use in downstream processing. For example, video favorability can be based on voice print analysis, facial recognition, kinematic analysis, and other feature analytics of evidence to be certified.
The greater a complexity of a piece of evidence, and so the more analytic tools that can be (and are) applied to it, the higher the favorability of the evidence may become. Additionally, evidence certification or favorability can include calculation based on authorities (e.g., users, participants, etc.) providing “approval” or support for the respective evidence. As a result, sources including a higher number of participants or authorities providing corroboration or otherwise validating, greater specificity (e.g., narrower in scope), more attributes (e.g., greater complexity), a longer historical record and/or more consistency to other evidence having a historical record, may have a higher favorability as compared to other evidence.
The certified evidence may be underpinned by a multilayered representation of evidence including, for example, (1) a digital structure of the evidence (e.g., a file, stream, etc.), (2) a tokenized representation of the evidence including various capture components contributing to the complexity of the evidence (e.g., audio, video, tactile, kinetic, chemical/molecular, etc.), and (3) a content representation layer including an abstraction of the content of the evidence. For example, the content representation layer may include an indicator for associated evidence linking it to a speech spoken by a particular person and including semantic content relating to a stance on domestic trade practice. While the example is at one level of abstraction, it is understood that the content representation layer may be as granular as desired (e.g., can include activity and/or object representations, mental constructs and interactions such as symbols, transactions, metaphysical interactions, etc.).
In some examples, the multilayered representation may be used for downstream treatment based on information in or across respective layers (e.g., for internal processing or as output via API and the like). For example, a simplified validity value (e.g., akin to a credit rating, etc.) may be generated through downstream processes. Additionally, the layers may be nested within one or more layers of another multilayered representation of evidence. For example, a video of a speech may include a multilayered representation of the speech within the multilayered representation of the video and the representations can be directly nested (e.g., as a recursive data structure, etc.) or via cross-references stored within a respective representation layer (e.g., memory address pointer, hash address pointer, hyperlink, etc.). In some examples, the multilayered representation can be used to identify relevant evidence to users during an analysis of user arguments (e.g., during a coached dialogue, etc.). Vulnerabilities in an argument which are related to stored evidence (e.g., evidence which may repair the argument vulnerability or evidence which may undercut the argument and be itself a vulnerability) can be identified by downstream processes and the associated evidence can be provided directly to a user.
FIG. 1A illustrates a three layer representation 10 of submitted evidence. A content data layer 12 receives, or is generated by, uploaded data from a user. Content data layer 12 includes raw content such as a video 13 of dialogue between two participants (e.g., a recorded interview, etc.). Content data layer 12 may be retrieved and processed by evidence certification and/or verification services (discussed below) or intake services and the like. Here, a video processing service retrieves content data layer 12.
A tokenized representation layer 14 may be generated based on content data layer 12 and video 13 contained within that layer. In some examples, tokenized representation layer 14 may be generated by video processing (where appropriate) services and the like. Tokenized representation layer 14 can include data for audio 18, image 20, kinematics 22, transcription 24, location 26, time 28, and other metadata components and the like. Contents of tokenized representation layer 14 can be used for content verification (e.g., perform kinematic analysis on kinematics 22, check location 26 and/or time 28 against similar data in other evidence that may conflict or support, etc.).
A content representation layer 16 can be produced from, or along with, tokenized representation layer 14 and content data layer 12. Content representation layer 16 includes data representing abstracted information related to content data layer 12. For example, content representation layer 16 can include discretized premises 30 identified from data in other layers, cross-references 32 which can associate three layer representation 10 of video 13 with other three layer representations 33 of uploaded evidence data, discrete abstractions 34, and external references 36 to associate three layer representation 10 with external content on, for example, the web.
In some examples, a validation data packet 40 can include various fields for performing and/or completing various content verification or evidence validation/certification processes. Validation data packet 40 may be structured as follows:















{



  sourceID:”content1”



  editorID:”user1”



  publicationchannelID:”publisher1”



  logicvalidatorID:”fallacy-check”



  rating:”high”



  ratingDate:”01-01-2018”



}










In particular, validation data packet 40 may correspond to data within layers 12, 14, or 16 (or nested three layer representations 33) and identifies a source for a piece of evidence to be verified. An editor identification field describes who is performing the verification (e.g., providing compute power, manually reviewing, etc.) and a publication channel denotes to where verification may be provided once complete. Further, the particular method of verification, here a check against various fallacies, may be included as well. While verification method here is a check against fallacies, various methods may be used based on the layer from which the validation data packet originates, verifier preference (e.g., manual checking of data, lending compute to a particular processes, etc.), or the particular component being verified (e.g., external reference 36 may be verified via different methods than premises 30, etc.). A calculated rating and rating date may also be stored within validation data packet 40.
Various systems can provide processes related to certification or content verification and may be performed by a central service or as a distributed workload (e.g., a “mining” operation, etc.) performed in whole or part by users and other participant (e.g., blockchain nodes, etc.). For example, a source monitoring system can guard against changes to cited evidence. Alerts and notifications can be generated based on changes to a source material. In some examples, thresholds can be set for alerts and notifications based on a significance or depth of change treatment to a source.
In one example, where evidence is classified as, for example, subjective or phenomenological, increased or decreased weight may be given to certain features of the evidence. Video components may be of increased value due to increased reliability of facial identity and kinematics, voice print analysis may be utilized and/or emphasized, and other treatments.
A news falsification (e.g., a “fake news” detection) system can use heuristics and content exploration to identify fake news and/or revoke certification of evidence. Novelty, style, common appeal, network relationships, and other direct and indirect features of the evidence may be used as heuristics for identifying false news and/or references.
A plagiarism detection process can certify content as original or as properly attributed. The plagiarism detection process can identify directly copied content (e.g., verbatim copying) as well as intentionally (or unintentionally) obfuscated plagiarized content based on premises, arguments, interrelationships, and the like. The above evidence certification systems and processes can be implemented as validation workloads performed by a centralized system or, in the case of a distributed system (discussed below), performed on an opt-in basis.
Evidence and/or users may be credentialed so that time and/or reputation of a user are linked to support or use of particular references. In some examples, a blockchain-based system can be used to provide an immutable record of evidence interactions and, additionally, allow for a user history to be tracked from the evidence interactions. A blockchain-based system can provide, for example and without imputing limitation, (1) immutability and decentralization, (2) distributed and opt-in workloads (e.g., “mining” operations, etc.), (3) trustless interactions (in other words, trust among participants is intrinsic to the closed system and a priori knowledge of users between users is unnecessary to support transactions/interactions), (4) tokenization of activities (e.g., interactions such as support or dispute of evidence is recorded on the blockchain in a discrete manner), (5) encryption layers for distributing content elements, and (6) smart contract operations for providing features such as time-lagged trust and post hoc auditability based on smart contract terms, etc. Credentials of a reference may depend upon which users have indicated support for the reference along with what other references (e.g., credibility, certification, etc.) each respective supporting user has also supported. The credential blockchains may additionally be available to downstream processes for analyzing references, users, or both.
In some examples, users can explore the data store through an interactive browser or user portal. For example, and without imputing limitation, a user may explore evidence by filtering on various filter parameters (e.g., source, relevance, validity certification, persuasiveness, other abstractions related to evidence). In some cases, the user can select from the explored evidence to “deploy” it or otherwise interact or use it for dialogue or review purposes (e.g., as part of a publication, etc.). Further, relevant content may be fed to users based on analysis of user arguments (e.g., entered through an interface) run against certified evidence in the data store. Additionally, users may perform “mining” or otherwise complete workloads in order to build reputation or a credit of some sort. In some examples, a mining operation may include providing compute for validating evidence by processing layer 2 attributes of evidence on the blockchain (e.g., voice or facial recognition, type classification, kinematic analysis, etc.) or layer 3 attributes such as performing a natural language processing as described in Application No. 62/645,114, entitled “System and Method for Processing Natural Language Arguments and Propositions,” hereby incorporated by reference in its entirety. In some examples, a mining operation may include other forms of content verification, including manual verification, and may require user access rights based on whether the user is an institution, reputation of the user, user history, and the like. For example, and without imputing limitation, a user may flag an image showing signs of tampering, indicate a failure to replicate a result of an experiment, dispute a “deep-fake” video or the like based on firsthand knowledge or with supporting evidence (e.g., located elsewhere on the blockchain, etc.). Through a user portal, users can apply various filters to review content related to selected subjects (e.g., entertainment, rhetorical, vetted, etc.). Various pieces of argument solution evidence can be cross-referenced so that argument can navigate between argument solution evidence related by, for example, shared factual bases, sources, participants, and the like.
Users may also review and/or comment on evidence. As discussed above, comments may be linked to user reputation via an immutable comment record for each user and/or an immutable record of user comments for each evidence item. In order to foster high quality user interaction, the user portal may include screening tests, training materials and tracking, points for good behavior, and the like.
In some examples, an API can provide integrations for third-party platforms.
FIG. 1B is an operating environment 100 in which a fact management system 102 processes evidence data for storage, upkeep, and retrieval. Processed evidence data is stored in a storage repository 106 which can be either remote or local to fact management system 102. In some examples, storage repository 106 may be an abstraction including multiple, specialized storage repositories access through a shared gateway service or portal.
In particular, users may access fact management system 102 through a computer 118 via a user portal 116. Through either direction by users or through automated means (e.g., schedulers, web crawling, etc.), fact management system 102 may retrieve evidence data from the Internet 104. Evidence data may include various digital sources such as text articles, video, image, webpage, and other data referenceable as evidence in debate, discussion, or other dialogue. Evidence data may be in the form of a multilayer content representation 122 as provided to fact management system 102. In some examples, fact management system 102 automatically converts all received evidence into a multilayer content representation 122 including three layers as discussed above. Freshly converted multilayer content representation 122 includes the evidence itself (e.g., layer 1) and may also include, in part or in whole, tokenized portions of the evidence (e.g., layer 2). Fact management system 102 may fill in layers 2 and 3 automatically or via distributed “mining” operations performed by users.
A source monitoring service 108 regularly certifies/recertifies, updates, and monitors evidence data stored in storage repository 106. Source monitoring service 108 can include schedulers, user controls, and the like. Further, source monitoring service 108 may include a comparator process for identifying changes to stored sources. Source monitoring service 108 includes alerting processes which may alert users to changes to sources based on user subscription (e.g., a user may subscribe to monitoring a particular source), user use of a monitored source, and the like.
An evidence certification service 110 can perform evidence certification processes as discussed above. For example, evidence certification may include classifying evidence data and performing specialized treatment, weighting, and/or processing of the classified evidence data.
A credentialing service 114 generates respective records for users and evidence data stored in storage repository 106. User credentials may document and provide scores, rankings, and the like based on user comment history, evidence data usage, and/or other user behavior. Evidence data credentials may include a history of changes (e.g., provided by source monitoring service 108), a history of user interaction with the evidence data (e.g., which users have used the evidence data and how), and other information. In some examples, credentialing service 114 may store and manage these records on a blockchain and/or as part of a blockchain network in order to provide an immutable record.
A news veracity classifier 112 can interface with the above discussed service in order to identify false and/or misleading evidence data (e.g., “fake news”, etc.). In some examples, identified false or misleading evidence data can be purged from storage repository 106. In some examples, identified false or misleading evidence data may be flagged and/or saved on another specialized data store.
Application programming interface (API) 120 provides input and output endpoints for fact management system 102. For example, API 120 may allow development of applications using data or processes of fact management system 102 such as website integrations and the like.
FIG. 1C depicts a fact management blockchain operating environment 130 which may include connection endpoints to fact management system 102 and incorporate at least portions of operating environment 100, respectively discussed above.
Fact management blockchain operating environment 130 includes a fact management blockchain network 132 which manages a blockchain 134. In particular, blockchain 134 includes an immutable record of uploaded evidence (e.g., facts, premises, etc.) as well as interactions with the uploaded evidence and may be storage repository 106 discussed above. Fact management blockchain network 132 may include multiple nodes, at least some of which may store copies of blockchain 134 for individual auditing and/or validation (not depicted).
A human user 136 or an institutional user 138 provides a respective sourced fact to fact management blockchain network 132. In some examples, the upload process may convert the sourced fact into a multilayer content representation 122 as discussed above in reference to FIG. 1B. Further, user 136 or institution 138 provides to a premise tagging process 140 a citation to the uploaded sourced fact. For example, the citation may be in an article for publication or the like. Premise tagging process 140 retrieves premise support and audit trail for the citation from fact management blockchain network 132. Further, fact management blockchain network 132 may record the retrieval on blockchain 134. The citation (e.g., article for publication) is then provided to editors 142 along with auditable and interactable assertions. For example, a complete audit trail of the citation (and other citations) can be provided to editors 142 for review. In some examples, the auditable and interactable asserts are automatically provided to edits 142 or may be actively requested by edits 142 from premise tagging process 140.
Editors 142 may upload smart contract rules to fact management blockchain network 132 to be added to blockchain 134. A smart contract may provide for automated performance (or review of items related to terms) of agreements memorialized over fact management blockchain network 132. Smart contract rules can include terms such as encrypted sources related to the provided citation, which may be decrypted once certain terms are met such as an amount of time following publication, particular users providing support (e.g., via user reputation or via supporting evidence uploaded to blockchain network 132, etc.), once a reputation threshold is obtained by user 136 or institution 138, compensation schemes, particularized user visibility and access, and the like.
Additionally, edits 142 may retrieve user reputation information from a reputation management process 146 to, for example, vet user 136 or institution 138 (e.g., to determine trustworthiness of a premise, an article author, or terms for a smart contract, etc.). Reputation management process 146 retrieves user history data from fact management blockchain network 132 by, for example, reviewing user interaction records within blockchain 134. Further, reputation management process 146 may provide reputation information fact management blockchain network 132 (for example, to fulfill terms of a smart contract, etc.) or otherwise provide “oracle” services to fact management blockchain network 132.
Editors 142 provide fact support content to publication 144. The fact supported content can include a complete or partial audit trail of asserts and facts within the content based on interactions with fact management blockchain network 132 discussed above. Further, publication 144 may then be provided as, or provide, auditable and filterable published content to audience 150. In some examples, audience 150 can retrieve premise audit information through, for example, hyperlinks and the like within the auditable and filterable published content which allow audience 150 to interface with blockchain 134 via fact management blockchain network 132 (e.g., in a read-only mode, etc.). Further, in some examples, audience 150 may filter content from publication 144 based on fact management blockchain network 132 information such as, for example and without imputing limitation, evidence certification for evidence related to (e.g., cited within) the auditable and filterable published content, reputation information of user 136 and/or institution 138 (e.g., filter based on an article author reputation), and various other content features retrievable or discernible from fact management blockchain network 132.
FIG. 1D illustrates a certified evidence data packet 160 for transmitting evidence to and from, for example, storage repository 106. In particular, certified evidence data packet 160 includes information for auditing content provided by storage repository 106. Certified evidence data packet 160 can be included as an attachment to a respective evidence data or may itself include the respective evidence data and, in effect, be a wrapper data structure for transmitting the evidence data.
A content type field 162 identifies a type of content received (e.g., video, image, text, etc.). Layer content field 164 may include tokenized representation layer 14 or associated content and/or content representation layer 16 and/or associated content. In some examples, layer content field 164 directly includes the content associated with layers 14 and 16. In some examples, layer content field 164 may instead include location information (e.g., addresses, hashes, etc.) for retrieving layer contents from storage repository 106 and the like. A cross-references field 166 includes other evidence to which certified evidence data packet 160 is linked via, for example, implicit reliance, direct reference, etc. In some examples, the other evidence is linked by an address or other identifier for independent retrieval. Further, a metadata field 168 may include other information of use to transmission systems and or processing systems (e.g., values related to operating system, performance indicators, routing policies, etc.).
A source identification field 170 can include information identifying a source of the content (e.g., an individual user, a website, another data repository, etc.). An editor identification field 172 can include identification information for one or more editors associated with the evidence data. A logic validator field 174 identifies operations for performing validation on the evidence data (e.g., fallacy checks, time checks, etc.). Further, a workload identification field 176, workload process identification field 178, and workload completion date field 180 provide identifying information for workloads performed, by which device (or user), and a time of completion to, for example, provide an audit trail for those reviewing work performed on the evidence data. In some examples, additional (e.g., optional) fields can be included within certified evidence data packet 160.
FIG. 2 depicts a credentialing service 200 which may be substantially similar to credentialing service 114 discussed above. Credentialing service 200 includes a user reputation management process 204, a blockchain credentialing interface 206, a user contribution support process 208, and a reviewer weighting process 210. User reputation management process 204 may interface with a user portal, such as user portal 116, and the like and can provide training services, screening, and the like.
Blockchain credentialing interface 206 includes interface access and/or API endpoints for managing one or more blockchains. In some examples, blockchain credentialing interface 206 includes a blockchain service node or the like that is a member of a public or private blockchain network.
User contribution support process 208 may include subservices and subsystems for managing users and/or assisting users in interacting with evidence data. For example, user contribution support process 208 includes a reviewer weighting subprocess 210 which can modify an effect of reviews on certification processes and the like. User contribution support process 208 may also exchange data with blockchain credentialing interface 206 in order to retrieve and/or store credentialing related data.
FIG. 3 depicts evidence certification service 300 which may include an evidence ranking process 304, a voice print identification process 306, a facial recognition process 308, a type classifier 310, and a kinematic analysis process 312. Processes of evidence certification service 300 may retrieve data from, for example, tokenized representation layer 14 of evidence. Evidence ranking process 304 may provide a sortable flag to evidence data based upon one or more types to which the evidence data conforms. Evidence data is assigned a type by type classifier 310, which may use natural language processing techniques and other processes of evidence certification system 300 to classify evidence data into one or more types as discussed above. Further, voice print identification process 306 provides voice print analysis and support (e.g., assigning a probability of veracity that evidence data is what it purports to be, etc.), which may also be used by ranking process 304. Facial recognition process 308 identifies individuals in evidence data such including video and/or image content. Kinematic analysis process 312 provides analytic support for video content of evidence in order to determine whether a video file has been tampered with and the like. In some examples, outputs of the above processes can feed back into tokenized representation layer 14 and/or into content representation layer 16 discussed above.
