Learning concepts through conversations in spoken dialogue systems 

Jia, et al.

PDF: buff.ly/2qmFsU9

In this work, we augment a spoken dialogue system with the ability to learn about new concepts by conversing with the user in natural language.

Bootstrapping semantic parsers from conversations 

Artzi, Zettlemoyer

Link: buff.ly/2qeatKF

In this paper, we present an approach for using conversational interactions of this type to induce semantic parsers. We demonstrate learning without any explicit annotation of the meanings of user utterances.

Elements of a Relational Theory of Datatypes 

Backhouse, Hoogendeijk

Link: buff.ly/2p2Qu13

The "Boom hierarchy" is a hierarchy of types that begins at the level of trees and includes lists, bags and sets. This hierarchy forms the basis for the calculus of total functions developed by Bird and Meertens, and which has become known as the "BirdMeertens formalism".

A tutorial on the universality and expressiveness of fold 

Hutton

PDF: buff.ly/2pP3ffE

In functional programming, fold is a standard operator that encapsulates a simple pattern of recursion for processing lists. This article is a tutorial on two key aspects of the fold operator for lists.

A commutative replicated data type for cooperative editing 

Prequiça, et al

PDF: buff.ly/2oT6qTE

This paper describes Treedoc, a novel CRDT design for cooperative text editing. An essential property is that the identifiers of Treedoc atoms are selected from a dense space.

CRDTs: Consistency without concurrency control 

Letia, Preguiça, Shapiro

PDF: buff.ly/2o7dONX

A CRDT is a data type whose operations commute when they are concurrent. Replicas of a CRDT eventually converge without any complex concurrency control. As an existence proof, we exhibit a non-trivial CRDT: a shared edit buffer called Treedoc. We outline the design, implementation and performance of Treedoc.

Designing a commutative replicated data type 

Shapiro, Preguiça

PDF: buff.ly/2oYIQXL

Commuting operations greatly simplify consistency in distributed systems. This paper focuses on designing for commutativity, a topic neglected previously. We show that the replicas of any data type for which concurrent operations commute converges to a correct value, under some simple and standard assumptions

Verified Peephole Optimizations for CompCert 

Mullen, Zuniga, Tatlock, Grossman

PDF: buff.ly/2o7iZhe

Transformations over assembly code are common in many compilers. These transformations are also some of the most bug-dense compiler components. Such bugs could be eliminated by formally verifying the compiler, but state-of-theart formally verified compilers like CompCert do not support assembly-level program transformations.

Improving the Static Analysis of Embedded Languages via Partial Evaluation 

Herman, Meunier

PDF: buff.ly/2oT5BtY

Programs in embedded languages contain invariants that are not automatically detected or enforced by their host language. We show how to use macros to easily implement partial evaluation of embedded interpreters in order to capture invariants encoded in embedded programs.

Improving Haskell Types with SMT 

Improving Haskell Types with SMT - Diatchki

PDF: buff.ly/2oT1qhL

We present a technique for integrating GHC’s type-checker with an SMT solver. The technique was developed to add support for reasoning about type-level functions on natural numbers, and so our implementation uses the theory of linear arithmetic

Type Systems as Macros 

Type Systems as Macros - Chang, Knauth, Greenman

Link: buff.ly/2iOXn2K

We present Turnstile, a metalanguage for creating typed embedded languages. To implement the type system, programmers write type checking rules resembling traditional judgment syntax. To implement the semantics, they incorporate elaborations into these rules. Turnstile critically depends on the idea of linguistic reuse.

Paper: Type Tailoring 

Type Tailoring - Greenman, Chang, Felleisen

PDF: buff.ly/2oT1Kxh

Type tailoring enables programmers to extend the rules of a type system without modifying the compiler. Programmers may thus codify additional knowledge about functions and methods in the form of a library of typing rules, which others may use without imposing any additional burden on their code or work flow
