Thousands of web APIs expose data and services that would be useful to access with natural dialog, from weather and sports to Twitter and movies. The process of adapting each API to a robust dialog system is difficult and time-consuming, as it requires not only programming but also anticipating what is mostly likely to be asked and how it is likely to be asked. We present a crowd-powered system...

There are more APIs than ever, and designing APIs that are usable by their target audience is difficult. Work at Microsoft has demonstrated that running controlled usability studies with participants from different personas and analyzing the results of these studies using the cognitive dimensions framework is effective at identifying and preventing usability problems in APIs. This paper present...

In this paper, we propose a strategy for implementing parallel-I/O interfaces portably and eeciently. We have deened an abstract-device interface for parallel I/O, called ADIO. Any parallel-I/O API can be implemented on multiple le systems by implementing the API portably on top of ADIO, and implementing only ADIO on diierent le systems. This approach simpli-es the task of implementing an API a...

Document-based code injection attacks, where-in malicious code (coined shellcode) is embedded in a document, have quickly replaced network-service based exploits as the preferred method of attack. In this paper, we present a new technique to aid in forensic and diagnostic analysis of malicious documents detected using dynamic code analysis techniques — namely, automated API call hooking and sim...

This white paper describes the tools, design flow, and verification of systems using Altera® FPGAs. It discusses the techniques of software simulation and hardware testing, and the challenges associated with them. This paper also describes the advantages of using the Hardware in the Loop (HIL) tool, which is part of Altera’s software tools, to simplify software simulation and hardware testing i...

Transforming programs between two APIs or different versions of the same API is a common software engineering task. However, existing languages support for such transformation cannot satisfactorily handle the cases when the relations between elements in the old API and the new API are many-to-many mappings: multiple invocations to the old API are supposed to be replaced by multiple invocations ...

In this paper, we describe Function Assistant, a lightweight Python-based toolkit for querying and exploring source code repositories using natural language. The toolkit is designed to help end-users of a target API quickly find information about functions through high-level natural language queries and descriptions. For a given text query and background API, the tool finds candidate functions ...

The development of REST APIs requires a great deal of time because developers have to address several issues to ensure a suitable design and the desired usability. This paper uses the model-driven approach to generate proper and functional REST APIs while focusing on the core aspects of REST and the consequences for the generation process. We present a method, which allows to design a REST API ...

Advanced multimedia applications call for integrated DBMS support, i.e., the integrated modeling, management, and interactive presentation of persistent multimedia documents. Generic services for the presentation of multimedia documents have to be available at the database clients. This includes continuous data delivery, realization of presentation layout, synchronization enforcement, and an e ...
