We present in this paper a constrained version of the problem of enumerating all maximal directed acyclic subgraphs (DAG) of a graph G. In this version, we enumerate stories, which are maximal DAGs whose sources and targets belong to a predefined subset of the nodes. First we show how to compute one story in polynomial-time, and we then describe two different algorithms to “tell” all possible s...

When is a story just a story? When is a story much more than a story? When is the story we think we know obscuring a much richer story? These questions and more lay at the root of my lifelong quest to understand the power of story. Growing up in a southern rural community, I learned the art of storytelling from my family and neighbors. I often heard with some admiration, “She sure is a good sto...

Morals play an important role in why storytelling developed, and help provide stories with structure. We describe a storytelling system which generates short stories that convey one of six common morals identified in Aesop’s fables. Morals are represented in terms of patterns of character emotions that arise during the course of a story. To evaluate the system’s effectiveness, we compare system...

The linguistic fund, that is, the actual lexical inventory of a language, is always considerably larger than the sum total of the contents of dictionaries for that language. It corresponds to all the possibilities of derivation and compounding-with the associated word-formation rules. The exploitation of the latter. within machine-readable dictionaries should therefore allow a far more accurate...

This paper challenges claims made by Scrum proponents when characterising the communicative nature of user stories: including being more 'authentic' because they comprise spoken language and that they are stories. We argue and decisively demonstrate that neither can be upheld. By incorrectly characterising user stories, we miss opportunities to understand what they are and how they work during ...

afzalodin badil khaghani shervani and nezami ganjavi are two major stylist poets who had profound influences on later poets. most of the khaghani’s poems are lucid and uncomplicated; but many ordinary people, and sometimes some of educated ones find it hard to understand some of his ballades because of different linguistic combinations and scientific terms he used in them. although, what makes ...

Nowadays, security is of great concern for any organization developing software systems for various requirements. Moreover, the same becomes more complicated during integration of security measures with agile software development methodology due to its lightweight informal nature. The requirements engineering is considered as one of the key element associated with any software development proce...
