Europeana

Europeana provides an online database of cultural heritage objects in the form of books, audio clips, photos, art, etc. It contains objects pertaining to history, fashion, maps, natural history, architecture, and more. The Europeana REST API allows developers to integrate the ability to search and retrieve objects from the database into their own applications.

Ghent University Academic Bibliography

The Ghent University Academic Bibliography provides bibliographic information describing scientific publications by Ghent University researchers. The Ghent University Academic Bibliography API provides a number of methods for developers to programmatically access that bibliographic information. The API is able to deliver feeds for bibliographic data from various departments and projects, access data describing single publications, subsets of the collection, or the collection in whole, search for publications using a variety of parameters, and much more.

Consumer Complaint Database

The Consumer Financial Protection Bureau (CFPB) works to make markets for financial products and services work for Americans through education, enforcement, and study. The CFPB’s Consumer Complaint Database catalogues the complaints received about financial products and services. The database consists of a single dataset, while providing multiple views through which to analyze the dataset. The Consumer Complaint Database is exposed through a RESTful API built on the Socrata Open Data API. The API allows applications to retrieve metadata about the dataset and views, query for views matching specified search criteria, or retrieve specific rows of data from the dataset and views.

Open PHACTS

Open PHACTS is a consortium focused on reducing the barriers to drug discovery in industry, academia, and for small businesses. The Open PHACTS API provides a developer interface for integrated querying of multiple publicly available pharmacological and physicochemical data sources. The API supports HTTP GET calls and returns data in a variety of formats, including JSON, XML, RDF, and more. An API key is required, but signup is free.

Harvard Faculty Finder

The Harvard Faculty Finder (HFF) provides a method by which students, faculty, administrators, and the general public can search for Harvard faculty members based on their research and teaching expertise. HFF is not a database of faculty profiles. Rather, it indexes and links existing information sources, making it possible to search and browse for faculty information across schools. Currently, only members of the Harvard community can make use of HFF, but that is expected to change later in the year.

ChemSpider InChi Resolver

The service provides tools for discovering and generating new InChIStrings and InChIKeys for chemical compounds. These International Chemical Identifiers conform to a format determined by the International Union of Pure and Applied Chemistry to uniquely name compounds across different chemistry research contexts. Functions include conversion between alternative identifier strings for the same compounds. API methods support generation of InChI strings, either by converting other formats, e.g., SMILE, or uploading or creating drawings of chemical structures. Resolver methods interpret InChIString or InChIKey values submitted with the request and return the associated chemical structures.

Ancient World Mapping Center

The Ancient World Mapping Center is an interdisciplinary research center located at the University of North Carolina at Chapel Hill. The Center promotes cartography, historical geography, and geographic information science within the field of ancient studies through research, teaching, and community outreach activities. The AWMC API allows users to browse, access, and interact with the AWMC database. The API uses RESTful calls and responses are formatted in GeoJSON and RDF.

Sigimera

Sigimera is a crises information platform that combines reports from official sources with on-the-ground information in order to support people in and around natural disasters. Sigimera can be used to host multimedia data such as images or videos of the scene after a natural disaster, or the statuses of useful locations (e.g. whether a hospital or airport is intact or over-crowded). Sigimera also provides a list of missing persons and their current statuses (missing/found/dead). The Sigimera API allows users to integrate information from Sigimera into other applications. RESTful calls can be used to retrieve crises, images, missing persons, and locations in a variety of data formats.

Enrycher

The service provides text analysis and processing at two levels. Shallow text processing reviews a sample to detect topic and keyword coverage and extract named entities, including people, places, organizations, and some numerical entities like percentages and amounts of money. Deep text processing attempts to resolve named entities detected with standard sources and linked datasets, including DBpedia, while also merging references to identical named entities, disambiguating word senses, and performing other complex semantic processing. API methods support identification of named entities within sample text and merging of separate references to a specific entity. Methods also detect matches for those entities within standard repositories, disambiguation of references to different entities, categorization, and export to RDF formats.
