      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

Simple mechanisms for low-budget natural language generation

2 posts in this topic

I'm hacking around on an IRC bot in my spare time, mostly as an interesting exercise in Javascript. It has some basic functionality but it just lacks that special something... so I want to teach it to talk.

 

Before we get too far into this, I should say that I'm fully aware that NLG is a massive field of research, and I'm not trying to pass any Turing tests here. I don't care if the generated "speech" even makes sense half the time; it's more for amusement than anything else.

 

My first inclination was to build a Markov model and use simple chains to construct sentences. Unfortunately, the space complexity of this is rather nasty, and the real killer is the amount of data needed to train the model adequately. I don't have a readily available corpus of plaintext to feed into the thing that suits the mood and personality I want to create.

 

The next obvious route would be to construct a Petri net for the language I want to speak. The major advantage is that this is a compact and fairly efficient way to do poor-man's NLG; the disadvantage is that hand-authoring and tuning a Petri net for nontrivial languages can be a huge time sink.

 

 

So I figured I'd poke around here and see if anyone knows of good algorithms for simple NLG that I might be able to take advantage of. I don't mind having to use a huge data set as long as the data is easily constructed and/or readily available in an easily digested format. Runtime is important since this is supposed to be a realtime conversational bot.

 

Non-goals: contextual recognition, memory, progressive refinement/learning, etc. It doesn't even have to do more than dumb keyword recognition for all I care.

 

 

Cheers!

I'd second your Markov model idea, and somehow try to work around the training problem.

 

If you build a simple semantic model using WordNet for example, you could reduce your training data required significantly.  So you'd end up learning at the high-level, <pronoun> <verb> <noun>, or possibly more detailed like <pronoun> <eat> <vegetable>.  I'm not sure how good NLP / NLG libraries are for Javascript but there are some awesome ones in Python that could help with this.

 

Anyway, cool project ;-)

You might want to look up what was done for the NaNoGenMo project (look on Github). It might give you a few ideas of some of the different approaches.
