Russian dataset for the reply recovery

This dataset is constructed from several Telegram chats in order to teach the model of prediction whether one message can be a reply for another or not. **Note:** the messages that actually replies are label with **zero**. The positive replies was aquaired based on natural `reply_to` Teleram markup. The negative case was aquaired by random sampling, which is suprisungly notably give some possibly `reply_to` combination, thus, making negative examples noisy. There are several chats: * balichat_woman - chats with woman from Bali * borussia_chat - football chat * chat_suicidnikov - the chat that dedicated the suicidal game "Siniy kit" * cotedazurchat - chat of immigrants in France * easypeasycodechat - chat of programmers * openwrt_ru - chat that dedicated to openWRT * orange_sosedi - chat of neighbors * sling38 - chat of yong moms * terrariaphone - chat of Terraria gamers The `test_data` was validated by crowdsource with Toloka.ai. The final validation was done by the authors, so it considered as gold test set.本数据集源自多组Telegram（电报）聊天记录，旨在训练可预测某条消息能否作为另一消息回复的模型。 **注**：实际作为回复的消息被标记为**0**。 正样本回复基于Telegram原生的`reply_to`标记机制获取；负样本则通过随机采样生成——令人意外的是，该采样方式会无意生成部分看似符合`reply_to`规则的组合，致使负样本引入噪声。 本数据集涵盖以下聊天群组： * balichat_woman：巴厘岛女性聊天群组 * borussia_chat：足球聊天群组 * chat_suicidnikov：针对自杀游戏《蓝色鲸鱼（Siniy kit）》的聊天群组 * cotedazurchat：法国蔚蓝海岸移民聊天群组 * easypeasycodechat：程序员聊天群组 * openwrt_ru：openWRT相关俄语聊天群组 * orange_sosedi：邻里聊天群组 * sling38：年轻妈妈聊天群组 * terrariaphone：《泰拉瑞亚（Terraria）》玩家聊天群组 本次的`test_data`已通过Toloka.ai平台完成众包验证，最终验证环节由数据集作者亲自完成，因此该测试集可被视作黄金标准测试集。
