In some cases the gall development disrupts the sprouting of leaves and the galls form a tuft on a bud. The gall is 1.0– 1.7 mm in width and 1.6–3.3 mm in length. Biology. Only the sexual generation is known which induces galls on Q. globosa. The gall development coincides with sprouting from mid- to late-March. Adults emerged under laboratory conditions immediately after the galls had been collected in the field and transferred to the laboratory. Distribution. Currently known only from Taiwan: Renai Township, Nantou County, and Heping District, Taichung City. The host-plant Q. globosa is endemic to Taiwan, thus C. globosus might be also endemic to Taiwan.Published as part of Tang, Chang-Ti, Sinclair, Frazer, Hearn, Jack, Yang, Man-Miao, Stone, Graham N., Nicholls, James A., Schwéger, Szabina & Melika, George, 2016, Eight new species of Cycloneuroterus Melika & Tang gallwasps from Taiwan and mainland China (Hymenoptera: Cynipidae: Cynipini), pp. 451-488 in Zootaxa 4088 (4) on pages 470-473, DOI: 10.11646/zootaxa.4088.4.1, http://zenodo.org/record/25966

The two gall morphotypes can be found in the same month. Biology. Only the sexual generation is known, inducing integral leaf galls on Quercus serrata Murray (= Q. glandulifera Blume) (section Quercus sensu stricto). Mature galls were collected in early March, adults emerging immediately after the galls were collected, in mid to late March. Distribution. Currently known only from Taiwan: Nantou County, Renai Township (Fig. 57). It is possible that this species is also distributed in continental China and Japan where Q. serrata occurs. Further research is necessary to establish the distribution of this species.Published as part of Tang, Chang-Ti, Melika, George, Yang, Man-Miao, Nicholls, James A. & Stone, Graham N., 2011, New species of oak gallwasps from Taiwan (Hymenoptera: Cynipidae: Cynipini), pp. 37-52 in Zootaxa 2865 on pages 38-42, DOI: 10.5281/zenodo.27742

Prominent part of ventral spine of hypopygium 4.5 x longer than broad, subapical setae not extending beyond apex of spine; 5–8 long white setae located along ventral part of hypopygium. Body length 2.3–2.4 mm (n = 4). Gall (Fig. 23). Galls develop as multichambered swellings within twigs of Quercus glauca (subgenus Cyclobalanopsis), similar to those induced by C. uberis. Larval chambers are 2.1–2.6 mm long and 1.2–1.6 mm in diameter. They always appear to be close to the twig surface and orientated along its axis, unlike those of C. uberis that can occur at varying depths and orientations. Biology. As for C. uberis, adult females of this asexual generation emerge during March when Quercus glauca is experiencing a flush of growth. No matching sexual generation has yet been identified. Distribution. Currently known only from Shihding District, New Taipei City, Taiwan. The only recorded host plant species— Q. glauca —occurs throughout East Asia.Published as part of Melika, George, Tang, Chang-Ti, Sinclair, Frazer, Yang, Man-Miao, Lohse, Konrad, Hearn, Jack, Nicholls, James A. & Stone, Graham N., 2013, A new genus of oak gallwasp, Cyclocynips Melika, Tang & Sinclair (Hymenoptera: Cynipidae: Cynipini), with descriptions of two new species from Taiwan, pp. 534-548 in Zootaxa 3630 (3) on pages 541-544, DOI: 10.11646/zootaxa.3630.3.8, http://zenodo.org/record/21944

The female holotype, 4 female and 7 male paratypes are deposited in NMNS, 3 female and 3 male paratypes in PDL, 1 female and 1 male in USNM, 4 female and 7 male paratypes in NCHU. Etymology. The shape, structure and location of the gall is very similar to that induced by a Western Palaearctic species, Andricus curvator Hartig, thus the species was named as “curvator-like” -- pseudocurvator. Diagnosis. Andricus pseudocurvator most closely resembles A. formosanus.

Gall (Figs 37 – 38). Individual galls approximately spherical, 2.4–3.6 mm in height (n= 9), and integral to leaf lamina. Galls appear as yellowish or brownish dots on leaves, cause swelling on both upper and lower surfaces of leaf, each contains single thin-walled larval chamber, 1.6–2.3 mm in diameter (n= 9). Outer wall of larval chamber attached to inner wall of surrounding gall tissue in both growing and mature galls. Galls usually occur separately on leaf and do not aggregate together. Young galls fleshy, yellowish to brownish, remaining soft as they mature. Biology. Only the sexual generation of this species is known, inducing integral leaf galls on Q. serrata. Mature galls were collected in early March, adults emerged immediately after the galls were collected, in mid and late March. Distribution. Currently known only from Taiwan: Nantou County, Renai Township and Taichung County, Heping Township (Fig. 57). In Taichung County, galls have been observed but no adults have been reared. It is possible that this species also occur in continental China and Japan, where Q. serrata occurs. Further research is necessary to establish the distribution of this species. Comments. The gall of this species occurs and develops at the same time as A. songshui, on the same organ of Q. serrata. Preliminary molecular data suggest this species is allied to the Eastern Palaearctic species A. symbioticus and the Western Palaearctic species A. inflator (J.Nicholls, unpublished data).Published as part of Tang, Chang-Ti, Melika, George, Yang, Man-Miao, Nicholls, James A. & Stone, Graham N., 2011, New species of oak gallwasps from Taiwan (Hymenoptera: Cynipidae: Cynipini), pp. 37-52 in Zootaxa 2865 on pages 42-46, DOI: 10.5281/zenodo.27742

#nowplaying-rs
No full text<p>The nowplaying-rs dataset features context- and content features of listening events. It contains 11.6 million music listening events of 139K users and 346K tracks collected from Twitter. The dataset comes with a rich set of item content features and user context features, as well as timestamps of the listening events. Moreover, some of the user context features imply the cultural origin of the users, and some others - like hashtags - give clues to the emotional state of a user underlying a listening event.</p>
<p>The dataset contains three files:</p>
<ul>
<li>user_track_hashtag_timestamp.csv contains basic information about each listening event. For each listening event, we provide an id, the user_id, track_id, hashtag, created_at </li>
<li>context_content_features.csv: contains all context and content features. For each listening event, we provide the id of the event, user_id, track_id, artist_id, content features regarding the track mentioned in the event (instrumentalness, liveness, speechiness, danceability, valence, loudness, tempo, acousticness, energy, mode, key) and context features regarding the listening event (coordinates (as geoJSON), place (as geoJSON), geo (as geoJSON), tweet_language, created_at, user_lang, time_zone, entities contained in the tweet).</li>
<li>sentiment_values.csv contains sentiment information for hashtags. It contains the hashtag itself and the sentiment values gathered via four different sentiment dictionaries: AFINN, Opinion Lexicon, Sentistrength Lexicon and vader. For each of these dictionaries we list the minimum, maximum, sum and average of all sentiments of the tokens of the hashtag (if available, else we list empty values). However, as most hashtags only consist of a single token, these values are equal in most cases. Please note that the lexica are rather diverse and therefore, are able to resolve very different terms against a score. Hence, the resulting csv is rather sparse. The file contains the following comma-separated values: <hashtag, vader_min, vader_max, vader_sum,vader_avg, afinn_min, afinn_max, afinn_sum, afinn_avg, ol_min, ol_max, ol_sum, ol_avg, ss_min, ss_max, ss_sum, ss_avg >, where we abbreviate all scores gathered over the Opinion Lexicon with the prefix 'ol'. Similarly, 'ss' stands for SentiStrength. </li>
</ul>
<p>Please note that user_track_hashtag_timestamp.csv and context_content_features.csv partly provide the same features. We deliberately chose to do so to be able to provide useable files that do not have to be matched and joined with each other to perform e.g., simple recommendation tasks.</p>
<p>Please also find the training and test-splits for the dataset in this repo. Also, Asmita provides prototypical implementations of a context-aware recommender system based on the dataset at https://github.com/asmitapoddar/nowplaying-RS-Music-Reco-FM.</p>
