   ABSTRACT     = {Cloud computing is a popular Internet-based computing 
      paradigm that provides on-demand computational services and 
      resources, generally offered by Cloud providers' REpresentational 
      State Transfer (REST) APIs. Developers use REST APIs by invoking 
      these APIs by their names and, thus, the lexicons used in the APIs 
      are important to ease the developers' comprehension. In this paper, 
      we study the lexicons and the linguistic (anti)patterns from 16 
      providers of REST Cloud Computing APIs. We observe that, although the 
      16 REST APIs describe the same domain (Cloud computing), contrary to 
      what one might expect, their lexicons do not share a large number of 
      common terms and 90% of the terms (3,561/3,947) are just used by one 
      provider. Thus, the APIs are lexically heterogeneous and there is not 
      a consensus on which terms to use in Cloud computing. Further, we 
      observe that the majority of the URIs, 54%, follow the Contextualised 
      Resource Names pattern, which is considered a good practice in REST 
      API design. However, a majority of the URIs, 62.82%, suffer from the 
      Non-pertinent Documentation antipattern. Thus, we present three main 
      contributions: 1) a tooled approach, called CloudLex, for extracting 
      and analysing REST Cloud computing lexicons; 2) our analysis of the 
      terms used in 16 REST APIs in 59,677 term occurrences; 3) our 
      analysis of the linguistic (anti)patters in more than 23,000 URIs of 
      the 142 services of the 16 Cloud providers. We also show that 
      CloudLex has an average precision of 84.82%, recall of 63.57%, and 
      F1-measure of 71.03% on one complete API, Docker Engine, which 
      confirms the accuracy of our semantic analyses for the detection of 
      linguistic (anti)patterns.}
